Okay, so I decided to raise chickens for my High School's FFA Organization. When I got them, I put them in a brooder box that belonged to my stepdad's cousin. I didn't realize that they would grow pretty fast. The box was suppose to be able to keep them for at least a month or two. But I had 20 birds, meat birds at that, that grew very fast. Well they got too big for their box and from a mixture of a) getting pretty crowded in there, and b) it getting pretty hot, they started picking their feathers off. Now I got them in a larger pen about two or three weeks ago and they're doing just fine now. Most of them have grown a good amount of feathers on their back, but some their butts and under-wing area are still pretty featherless. They have little feather stubs. I'm just wanting to know if their feathers will grow back comepletely, because I have to show them in about two monthes. And if they will, is there a way to make them grow faster? My Ag teacher said to put a teaspoon of corn oil in their food, but I don't think he knows much about chickens, he's more of a pig specialist. And my grandpa told me to put a little bit of sugar in their water. Please help a new chicken owner out! I'm clueless and I worry about my peeps.
