With the introduction of commercial grade feed a lot of these lessons from the past are falling to the wayside. During a long term SHTF situation, this type of information will probably come in handy.
Protein, one great secret of profitable poultry-keeping is, that hens cannot thrive and lay without a considerable quantity of protein, and therefore if they cannot obtain a sufficient quantity in the form of insects, it must be supplied in meat, which, minced small, should be given daily and also to all fowls in winter, as insects are then not to be had.
Mr. Baily says: “Do not give fowls meat, but always have the bones thrown out to them after dinner; they enjoy picking them, and perform the operation perfectly. Do not feed on raw meat; it makes fowls quarrelsome, and gives them a propensity to peck each other, especially in moulting time if the accustomed meat be withheld.” Take care that long pieces of membrane, or thick skin, tough gristle or sinew, or pieces of bone, are not left sticking to the meat, or it may choke them, or form a lodgment in the crop.
