CHAPTER VIII.

STOCK, BREEDING, AND CROSSING.

Keep only good, healthy, vigorous, well-bred fowls, whether you keep

them to produce eggs or chickens, or both. The ill-bred mongrel fowls

which are so commonly kept, are the most voracious, and consume larger

quantities of food, without turning it to any account; while well-bred

fowls eat less, and quickly convert that into fat, flesh, and eggs.

"Large, well-bred fowls," says Mr. Edwards, "do not consume more food

than ravenous, mongrel breeds. It is the same with fowls as with other

stock. I have at this moment two store pigs, one highly bred, the other

a rough, ill-bred animal. They have, since they left their mothers, been

fed together and upon the same food. The former, I am confident (from

observation), ate considerably less than the latter, which was

particularly ravenous. The former pig, however, is in excellent

condition, kind, and in a measure fat; whereas the latter looks hard,

starved, and thin, and I am sure she will require one-third more food to

make bacon of."

For the amateur who is content with eggs and chickens, and does not long

for prize cups, excellent birds possessing nearly all the best

characteristics of their breeds, but rendered imperfect by a few

blemishes, may be purchased at a small cost, and will be as good layers

or chicken-producers, and answer his purpose as well as the most

expensive that can be bought.

The choice of breed must depend upon the object for which the fowls are

kept, whether chiefly for eggs or to produce chickens, or for both; the

climate, soil, and situation; the space that can be allotted to them;

and the amount of attention that can be devoted to their care. If fowls

are to be bred for exhibition, you must be guided by your own taste,

pocket, and resources, as well as by the suitability of the situation

for the particular breed desired. The advantages, disadvantages, and

peculiarities of the various breeds will be described under their

respective heads.

In commencing poultry-keeping buy only young and healthy birds. No one

sign is infallible to the inexperienced. In general, however, the legs

of a young hen look delicate and smooth, her comb and wattles are soft

and fresh, and her general outline, even in good condition (unless when

fattened for the table), rather light and graceful; whilst an old one

will have rather hard, horny-looking shanks; her comb and wattles look

somewhat harder, drier, and more "scurfy," and her figure is well filled

out. But any of these signs may be deceptive, and the beginner should

use his own powers of observation, and try and catch the "old look,"

which he will soon learn to know.

All authorities agree that a cock is in his prime at two years of age,

though some birds show every sign of full vigour when only four months

old. It is agreed by nearly all the greatest authorities that the ages

of the cocks and hens should be different; however, good birds may be

bred from parents of the same age, but they should not be less than a

year old. The strongest chickens are obtained from two-year old hens by

a cockerel of about a year old; but such broods contain a disproportion

of cocks, and, therefore, most poultry-keepers prefer to breed from

well-grown pullets of not less than nine months with a cock of two years

of age. The cock should not be related to the hens. It is, therefore,

not advisable to purchase him from the same breeder of whom you procure

the hens. Do not let him be the parent of chickens from pullets that are

his own offspring. Breeding in-and-in causes degeneracy in fowls as in

all other animals. Some birds retain all their fire and energy until

five or even six years of age, but they are beyond their prime after the

third, or at the latest their fourth year; and should be replaced by

younger birds of the same breed, but from a different stock.

Poultry-breeders differ with respect to the proper number of hens that

should be allowed to one cock. Columella, who wrote upon poultry about

two thousand years ago, advised twelve hens to one cock, but stated that

"our ancestors did use to give but five hens." Stephanus gave the same

number as Columella. Bradley, and the authors of the "Complete Farmer,"

and the article upon the subject in "Rees's Cyclopaedia," give seven or

eight; and those who breed game-cocks are particular in limiting the

number of hens to four or five for one cock, in order to obtain strong

chickens. If fine, strong chickens be desired for fattening or breeding,

there should not be more than five or six hens to one cock; but if the

supply of eggs is the chief consideration, ten or twelve may be allowed;

indeed, if eggs are the sole object, he can be dispensed with

altogether, and his food saved, as hens lay, if there be any difference,

rather better without one.

The russet red is the most hardy colour, white the most delicate, and

black the most prolific. General directions for the choice of fowls, as

to size, shape, and colour, cannot be applicable to all breeds, which

must necessarily vary upon these points. But in all breeds the cock

should, as M. Parmentier says, "carry his head high, have a quick,

animated look, a strong, shrill voice (except in the Cochins, which have

a fuller tone), a fine red comb, shining as if varnished, large wattles

of the same colour, strong wings, muscular thighs, thick legs furnished

with strong spurs, the claws rather bent and sharply pointed. He ought

also to be free in his motions, to crow frequently, and to scratch the

ground often in search of worms, not so much for himself, as to treat

his hens. He ought, withal, to be brisk, spirited, ardent, and ready in

caressing the hens, quick in defending them, attentive in soliciting

them to eat, in keeping them together, and in assembling them at night."

To prevent cocks from fighting, old Mascall, following Columella, says:

"Now, to slacke that heate of jealousie, ye shall slitte two pieces of

thicke leather, and put them on his legges, and those will hang over his

feete, which will correct the vehement heate of jealousie within him";

and M. Parmentier observes that "such a bit of leather will cause the

most turbulent cock to become as quiet as a man who is fettered at the

feet, hands, and neck."

The hen should be of good constitution and temper, and, if required to

sit, large in the body and wide in the wings, so as to cover many eggs

and shelter many chickens, but short in the legs, or she could not sit

well. M. Parmentier advises the rejection of savage, quarrelsome, or

peevish hens, as such are seldom favourites with the cocks, scarcely

ever lay, and do not hatch well; also all above four or five years of

age, those that are too fat to lay, and those whose combs and claws are

rough, which are signs that they have ceased to lay. Hens should not be

kept over their third year unless very good or choice. Hens are not

uncommon with the plumage and spurs of the cock, and which imitate,

though badly, his full-toned crow. In such fowls the power of producing

eggs is invariably lost from internal disease, as has been fully

demonstrated by Mr. Yarrell in the "Philosophical Transactions" for

1827, and in the "Proceedings of the Zoological Society" for 1831. Such

birds should be fattened and killed as soon as observed.

By careful study of the characteristics of the various breeds, breeding

from select specimens, and judicious crossing, great size may be

attained, maturity early developed, facility in putting on flesh

encouraged, hardiness of constitution and strength gained, and the

inclination to sit or the faculty of laying increased.

Sir John Sebright, speaking of breeding cattle, says: "Animals may be

said to be improved when any desired quality has been increased by art

beyond what that quality was in the same breed in a state of nature. The

swiftness of the racehorse, the propensity to fatten in cattle, and to

produce fine wool in sheep, are improvements which have been made in

particular varieties in the species to which these animals belong. What

has been produced by art must be continued by the same means, for the

most improved breeds will soon return to a state of nature, or perhaps

defects will arise which did not exist when the breed was in its natural

state, unless the greatest attention is paid to the selection of the

individuals who are to breed together."

The exact origin of the common domestic fowl and its numerous varieties

is unknown. It is doubtless derived from one or more of the wild or

jungle fowls of India. Some naturalists are of opinion that it is

derived from the common jungle fowl known as the _Gallus Bankiva_ of

Temminck, or _Gallus Ferrugineus_ of Gmelin, which very closely

resembles the variety known as Black-breasted Red Game, except that the

tail of the cock is more depressed; while others consider it to have

been produced by the crossing of that species with one or more others,

as the Malay gigantic fowl, known as the _Gallus giganteus_ of Temminck,

Sonnerat's Jungle Fowl, _Gallus sonneratii_, and probably some other

species. At what period or by what people it was reclaimed is not known,

but it was probably first domesticated in India. The writers of

antiquity speak of it as a bird long domesticated and widely spread in

their days. Very likely there are many species unknown to us in Sumatra,

Java, and the rich woods of Borneo.

The process by which the various breeds have been produced "is simple

and easily understood," says Mr. Wright. "Even in the wild state the

original breed will show some amount of variation in colour, form, and

size; whilst in domestication the tendency to change, as every one

knows, is very much increased. By breeding from birds which show any

marked feature, stock is obtained of which a portion will possess that

feature in an _increased degree_; and by again selecting the best

specimens, the special points sought may be developed to almost any

degree required. A good example of such a process of development may be

seen in the 'white face' so conspicuous in the Spanish breed. White ears

will be observed occasionally in all fowls; even in such breeds as

Cochins or Brahmas, where white ear-lobes are considered almost fatal

blemishes; they continually occur, and by selecting only white-eared

specimens to breed from, they might be speedily fixed in any variety as

one of the characteristics. A large pendent white ear-lobe once firmly

established, traces of the white _face_ will now and then be found, and

by a similar method is capable of development and fixture; whilst any

colour of plumage or of leg may be obtained and established in the same

way. The original amount of character required is _very_ slight; a

single hen-tailed cock will be enough to give that characteristic to a

whole breed. Any peculiarity of _constitution_, such as constant laying,

or frequent incubation, may be developed and perpetuated in a similar

manner, all that is necessary being care and time. That such has been

the method employed in the formation of the more distinct races of our

poultry, is proved by the fact that a continuance of the same careful

selection is needful to perpetuate them in perfection. If the very best

examples of a breed are selected as the starting-point, and the produce

is bred from indiscriminately for many generations, the distinctive

points, whatever they are, rapidly decline, and there is also a more or

less gradual but sure return to the primitive wild type, in size and

even colour of the plumage. The purest black or white originally,

rapidly becomes first marked with, and ultimately changed into, the

original red or brown, whilst the other features simultaneously

disappear. If, however, the process of artificial selection be carried

too far, and with reference _only to one_ prominent point, any breed is

almost sure to suffer in the other qualities which have been neglected,

and this has been the case with the very breed already mentioned--the

white-faced Spanish. We know from old fanciers that this breed was

formerly considered hardy, and even in winter rarely failed to afford a

constant supply of its unequalled large white eggs. But of late years

attention has been so _exclusively_ directed to the 'white-face,' that

whilst this feature has been developed and perfected to a degree never

before known, the breed has become one of the most delicate of all, and

the laying qualities of at least many strains have greatly fallen off.

It would be difficult to avoid such evil results if it were not for a

valuable compensating principle, which admits of _crossing_. That

principle is, that any desired point possessed in perfection by a

foreign breed, may be introduced by crossing into a strain it is desired

to improve, and every other characteristic of the cross be, by

selection, afterwards bred out again. Or one or more of these additional

characteristics may be also retained, and thus a _new variety_ be

established, as many have been within the last few years."

Size may be imparted to the Dorking by crossing it with the Cochin, and

the disposition to feather on the legs bred out again by judicious

selection; and the constitution may be strengthened by crossing with the

Game breed. Game fowls that have deteriorated in size, strength, and

fierceness, by a long course of breeding in-and-in, may have all these

qualities restored by crossing with the fierce, powerful, and gigantic

Malay, and his peculiarities may be afterwards bred out. The size of the

eggs of the Hamburg might very probably be increased without decreasing,

or with very slightly decreasing, the number of eggs, by crossing with a

Houdan cock; and the size would also be increased for the table. The

French breeds, Creve-Coeur, Houdan, and La Fleche, gain in size and

hardiness by being crossed with the Brahma cock. The cross between a

Houdan cock and a Brahma hen "produces," says the "Henwife," "the finest

possible chickens for market, but not to breed from. Pure Brahmas and

Houdans alone must be kept for that purpose; I have always found the

second cross worthless."

In crossing, the cockerels will more or less resemble the male, and the

pullets the hen. "Long experience," says Mr. Wright, "has ascertained

that the male bird has most influence upon the colour of the progeny,

and also upon the comb, and what may be called the 'fancy points,' of

any breed generally; whilst the form, size, and useful qualities are

principally derived from the hen."

Breed only from the strongest and healthiest fowls. In the breeding of

poultry it is a rule, as in all other cases of organised life, that the

best-shaped be used for the purpose of propagation. If a cock and hen

have both the same defect, however trifling it may be, they should never

be allowed to breed together, for the object is to improve the breed,

not to deteriorate it, even in the slightest degree. Hens should never

be allowed to associate with a cock of a different breed if you wish to

keep the breed pure, and if you desire superior birds, not even with an

inferior male of their own variety. "No time," says Mr. Baily, "has ever

been fixed as necessary to elapse before hens that have been running

with cocks of divers breeds, and afterwards been placed with their

legitimate partners, can be depended upon to produce purely-bred

chickens; I am disposed to think at least two months. Time of year may

have much to do with it. In the winter the escape of a hen from one run

to the other, or the intrusion of a cock, is of little moment; but it

may be serious in the spring, and destroy the hopes of a season." Many

poultry-keepers separate the cocks and hens after the breeding season,

considering that stronger chickens will be thereby obtained the next

season. Where there is a separate house and run for the sitting hen this

can be conveniently done when that compartment is vacant. In order to

preserve a breed perfectly pure, it will be necessary, where there is

not a large stock of the race, to breed from birds sprung from the same

parents, but the blood should be crossed every year by procuring one or

more fowls of the same breed from a distance, or by the exchange of eggs

with some neighbouring stock, of colour and qualities as nearly allied

as possible with the original breed.
