Buying guineas was a little more difficult than I had expected. With chickens you just down to the local feed and fertilizer in the early spring and buy the chicks you want, or place an order with various websites that sell chicks online. With guineas you get on a waiting list at the local feed […]
Experiments have demonstrated that what may be called the gastric juice in fowls has not sufficient power to dissolve their food, without the aid of the grinding action of the gizzard. Before the food is prepared for digestion, therefore, the grains must be subjected to a triturating process; and such as are not sufficiently bruised in this manner, before passing into the gizzard, are there reduced to the proper state, by its natural action.
The action of the gizzard is, in this respect, mechanical; this organ serving as a mill to grind the food to pieces, and then, by means of its powerful muscles, pressing it gradually into the intestines, in the form of pulp. The power of this organ is said to be sufficient to pulverize hollow globules of glass in a very short time, and solid masses of the same substance in a few weeks.
The rapidity of this process seems to be proportionate, generally, to the size of the bird. A chicken, for example, breaks up such substances as are received into its stomach less readily than the capon; while a goose performs the same operation sooner than either. Needles, and even lancets, given to turkeys, have been broken in pieces and voided, without any apparent injury to the stomach. The reason, undoubtedly, is, that the larger species of birds have thicker and more powerful organs of digestion.

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.”
