We've had our new hen living side-by-side but separated from our original hen (they're about the same size and same age) for a few weeks now and they are beginning to get used to each other. We let them wander around outside at opposite ends of the backyard and they seem content to stay away from each other. However, when they do get close to each other, they still want to do chicken karate on each other. While we understand that they will fight a bit to establish their pecking order, we're not sure how long a hen fight should be allowed to last. We got some bad advice from a breeder when we first brought the new girl home and we introduced them immediately and allowed them to fight for about 15 minutes and there was quite a bit of blood. We now know that introducing new birds is a lengthy process, but we still don't know what to expect when we introduce them again face-to-face. How long should the battle of the beaks go on for and how bloody do these battles normally get? Thanks for any advice you can give us!
