I have 5 hens that i got as day olds on August 18th. They have always lived together and recently started laying. We get 4 eggs a day. Today when i was out with them i noticed that the comb of one was bloody and saw another hen attack its comb when it was in run. Is this normal and any advice? She is eating and drinking and the aggression is not constant.
The hens go for the head, and they peck HARD. They're always after the head. I've seen several combs pecked badly. I've even had hens missing fingers from their combs due to pecking order. It's chickens in a run. When they're free ranging, and are rarely ever in each other's space, there is never this problem. I've dealt with this problem countless times, with different chickens and flocks and in different runs. I've even experimented with what run has the least amount of pecking issues.
