It seems that each group of chickens will have their own unique traits, preferences & habits. This latest batch of chicks has gotten into a bad habit of feather picking/eating, and I'd like suggestions as to how to get them to stop. This is a group of about 30 chicks, mostly all pullets, several different large production breeds. They are about 10 weeks old, they've been doing this since they began growing feathers along their backs. That's where they're doing most of the picking. They're not breaking the skin, just pecking at and I guess eating the feathers as they emerge. It's interesting to note that it's the Dark Brahamas and the Partridge Rocks getting picked upon the most. You'd think the Buff Orps would be among the victims but they look fine. I can't tell who in particular is doing the most picking. They are eating the same chick starter I've given all my other chicks. I don't want to switch to a more expensive higher-protein feed, I don't think lack of protein is the problem and I couldn't afford it anyway. They stay in an outdoor coop and have lots of dirt to scratch in, I've also been giving them leafy weeds to peck at to keep them occupied. I've separated some of the baldest chicks, hoping their backs can grow feathery again and I can then return them to the group. What else could I put on their backs to discourage picking by the others?
