We got our chickens from egg factory, thus meaning that all chickens were shabby. Now most of them look fine, because it has been around 5 months since we got them, but there is a bad habit in many chickens. They tend to pluck each other, because in factory's they don't have a lot of space and that's their only entertainment. About 2 month ago we got a rooster. At the very first day I noticed, that some chicken pluck him. Looked like they wanted to fight. As far as I have seen, it has stopped, but the feathers on my roosters head have been plucked out and new awns can't grow out, because they get plucked out all the time. However, rooster is not the only who gets his new awns plucked out. There are two more chickens, who haven't managed to regrow feathers, due to some chickens plucking their awns. About month ago, one of the chickens hatched 4 chicks, but we separated them from flock, so the chick don't get killed. But they are growing quickly and sooner or later we will have to reintroduce them to flock. The problem is following. 2 days ago I walked in barn and saw an awful thing. One of the two chickens, who haven't regrown their feathers, was plucked so hard, that its tail was all in blood. I was disgusted by the fact, that there is a chicken, who has done that. Luckily, I didn't had to guess the chicken, which was guilty, because of the blood on its beak. Later that day I took that chicken out of the barn and asked my dad to kill it. (By the way, the chicken who was bleeding is fine now) However, yesterday and today I have noticed, that there is still some chicken/s who pluck feathers, because there was two awns plucked on roosters head and an awn plucked from one of the chickens with bare tail. Now I am concerned about reintroducing the new chicks to flock, because I don't want them to be plucked. I have been considering the idea of butchering most of the chickens, or at least those, who don't look neat, because I have observed, that the less neat looking chickens pluck others more, while tidy looking ones tend to do their stuff instead of plucking awns and feathers. The real question is - is that necessary to exterminate the plucking habit?
