Our Polish Silkie, Golda, had a decently sized chunk of her head plume feathers missing and slightly bloody when I arrived home from work last Wednesday. I have no idea how it happened or if it was from one of the other chickens. I immediately went online, found out how to treat her, and removed her from the coop, away from the 5 other chickens we have in there. We've had her isolated in her own pen since then. She seems to be healing just fine, and I see a tiny amount of regrowth on her sad little bald spot, but it still looks like an injury. I'm not sure how long she should be away from the flock, and if there is a best way to reintroduce her when the time comes. Any information or experiences from other chicken parents would be really appreciated. TY in advance!!!
