What can I feed my chickens--mostly young or mature hens--that has animal protein in it? I am having a problem with them picking pin feathers from each other, where the roo tore/rubbed their feathers off their backs and "shoulders" of their wings, and now they can't grow back, even tho I have removed the roo, because every time a pin feather peeks out, one of them picks it off. It has been suggested to me that they need more "animal protein", that they are low in protein, but that feeds these days have mostly vegetable protein in them, which isn't as good as animal protein. Where can I get animal protein. A person I know slightly who raises about 300 layers says to feed road kill to them. He said he picks up possums, coons, etc, that have been hit on the road, and boils them up in an old pot, --on an outside fire I assume!!! --and feeds them to the chickens--hair, guts and all. He said he even found a deer once, and tossed it on an old outside BBQ and cooked it some, and the chickens loved it. I can't quite bring myself to collecting road kill--let alone cooking it--so am wondering what other suggestions for animal protein some of you have?? I have put "saddles" on the worst ones, and have also taken out the rooster, hoping that feathers will get a chance to grow back under the saddles, but would like to address the "lack of sufficient protein" issue, also.
