I've had chickens for over a year now and have got a lot of advice from the threads on here, but I can't find anything about what happened today! I have 5 chickens, we got them in pairs but one of the first two was killed by a dog a few months ago. We hatched the last two and they've grown up together, now about 10 months old. Theyre inseparable usually - an aracuna and a pekin. But today I went down and they were fighting quite viciously and and the pekin ended up bleeding from her comb. Why would they suddenly start to fight, and how do I treat the bleeding so it doesnt attract more pecks from the others in the flock? Thanks!
