I have several breeds of chickens. They have all been together for a few months. I have a couple of Langshans (larger but younger than some) that have some broken tail feathers. I have read to pull them out. The are too many and I tried to pull out the worst one. I couldn't and I don't want to hurt him further by continuing to try. I have read I can put blue kote on it but I didn't know if it would be ok with the broken tail blood feathers still there. I had made an apron that covered the tail but they managed to get under it and make it worse. The chicken with the worst tail has been seperated. I hate for him to be alone and he gets upset when it's breakfast time and he misses day old bread. I give him some but it's not the same. He is so calm and sweet, probably why he gets picked on. He only seems in pain when I tried to pull out the feather. So if I leave the broken feathers, will it be painful for him? Is it ok to put the blue kote on them? And will they grow out?
