I have 12 chickens in a 12x12 run and 4x12 coop. They free range for 4-7 hours everyday. A month or so ago, one of our two Barred Rocks died. We don't know why. Right before that, the other Barred Rock started to really bully one of the other chickens. The Barred Rocks were always a little on the bully side. Maybe the other chicken was sick, so the remaining Barred Rock went a little overboard? Slowly 3 other hens joined in the bullying, I think only when her head was already bloody. I haven't seen her head bloody other than that one time. The chicken that is being bullied has always been one of the shy chickens in the flock. I wanted to pull out one or two of the worst bullies and wondered if I have to separate them where they can't been seen. I was going to just put them in separate crates in the run, but then of course they could see and be seen by the rest of the flock. Will this work if they can still see each other? How do people come up with an alternate predator safe place to put a chicken? Thanks for any help?
