CHAPTER XV

Hard Coal Ashes, Oyster Shell, and Grit

As stated in the chapter on “Anthracite Coal Ashes,” ashes have

entirely taken the place of charcoal on The Corning Egg Farm. They

are fed in hoppers with the Grit and Oyster Shell. These hoppers are

divided into three compartments, and are automatic in feeding down the

ingredients, in small quantities at a time, for Biddy’s use.

It is very essential to supply the hen with the proper grinding

material for operation in her mill, for, from the crop, what she takes

into her system in the way of grain, etc., is passed into the gizzard,

where she places a certain amount of hard, sharp stones, to use as

mill stones, and this great muscular organ then puts the food into the

proper condition for her to assimilate it.

The Grit placed in the hoppers is hard and sharp. Ordinary pebbles are

of no use to Biddy in preparing her food for digestion. There are a

great many different grits on the market sold through Poultry Supply

Houses, and by the manufacturers themselves. Where it is possible to

procure Grit having the essentials as already described, and carrying a

good percentage of lime, it adds very materially to the desirability

of the Grit.

Oyster Shell occupies the third compartment of the hoppers, this

supplying the hen with the lime necessary for her own system and for

the shell of the egg. It should be seen to that the Oyster Shell is

free from dust, and rather coarse as to its size. This represents an

economy because there is so little waste by the fowls when the Shell is

fed to them in this condition. The lack of lime in the system of the

hen is one of the reasons for soft shelled eggs, and the lack of lime

in the ingredients fed to a young chick means soft bones, which shows

most decidedly in leg weaknesses.

Where the hen is supplied with the full quantity of the ingredients

which give her lime, she turns out eggs which you might term “well

shelled” and this adds materially to the appearance of the egg, and,

consequently, helps to give it a better grading.
