ARTIFICIAL BROODING

The practice of brooding poults artificially is becoming more popular and

is usually more successful than brooding with turkey hens. The methods

used in artificial brooding are very similar to those used in raising

chicks, which are discussed in Farmers' Bulletin 1538, Incubation and

Brooding of Chickens. However, one point of great importance in brooding

poults artificially is to make sure that they do not crowd together

while in the brooder house. This can be avoided by frequent attention,

by providing an even temperature, and by having good ventilation in the

brooder house. A colony house or permanent brooder house that is suitable

for brooding chicks is equally suitable for turkeys, but fewer birds

should be put in the house, as turkey poults are larger than chicks.

Between 75 and 125 poults should be placed under one 52-inch hover in the

average colony brooder House. Larger hovers and larger brooding rooms

will accommodate 225 poults or more, but only an experienced operator

should attempt; to raise groups larger than 150. The prevailing custom

is to use brooder stoves in portable colony houses or permanent brooding

quarters.

The colony houses may be moved several times each season, thereby giving

the poults plenty of free range on clean soil. Since blackhead is closely

associated with insanitary conditions, special effort must be made to

keep the houses, runs, and yards clean. If permanent brooder houses are

used, a floor of concrete from 12 to 14 feet wide or a small gravel or

cinder-floored yard is often used in front of the house. A skeleton

framework covered with to 1-inch-mesh wire may also be used to floor the

outside run either with the permanent brooder houses or with the colony

houses (fig. 11). Poults are regularly confined to this small yard for

the first 8 weeks and in some cases have been successfully reared to

market age in it. However, a clean yard containing growing green feed is

an advantage in brooding. If it is used only for about 8 weeks each year,

there seems little danger of contamination.

The brooder and brooder house should be operated to keep the young

turkeys comfortable. A dim light under or above the hover at night has

a quieting effect on the poults. The temperature should be high enough

to keep the poults comfortable but not high enough to be detrimental to

their health. When the poults are first put into the colony house with

the brooder stove, the temperature 3 inches above the floor under the

hover should be from, 95° to 110° F. This temperature should be lowered

gradually as the poults get larger until they are 6 or 8 weeks old, when

they require little or no heat, especially in the daytime. It is a common

practice in cold weather to keep the general room temperature at the

floor rather high, about 75°, to prevent crowding. The exact temperature,

however, is of minor importance provided the poults are kept comfortable

and good ventilation is maintained. The poults, if comfortable, will

be active and contented. This is the real test of temperature. All

warm points and surfaces except those at the brooder itself should be

eliminated. Free access from all parts of the brooder room to the hover

must be provided. All corners in the brooding room, especially back of

the hover, should be rounded, preferably by using 1/2-inch-mesh poultry

wire. A fence of the same material should be set up around the hover

for the first 2 or 3 days until the poults become accustomed to their

surroundings and learn to return to the source of heat. Flat roosts 2

to 2-1/2 inches wide and slightly tilted up at the rear may be placed

at graduated levels in the brooder house when the poults are from 2 to

3 weeks old, to encourage them to begin roosting at an early age. This

provision lessens the danger of night crowding. The front roost should be

6 inches above the floor and each of the others a few inches higher than

the one in front of it and about 8-1/2 inches apart, center to center.
