I'd be really grateful for your opinions as I'm very worried about my hens. I have one older hen and 9 pullets. One of the pullets has started laying. They both go in the same next box although there is a choice of three. They argue over it the larger hen pecked the younger's crest, drawing blood, two days ago. Yesterday, after much noisy consternation by both parties, they both managed to lay without a fight. But today, there is blood all over the nest box where the older has badly pecked the younger's crest. I don't know why they don't use the other nest boxes - they are all the same and I have changed the bedding so it is nice and fresh. I don't have another shed for quarantine and I am very worried the violence will escalate. Any ideas?
