I need advice with integrating new chickens. I have a flock of 15 that are about a month away from laying. About a month ago, I got four other chickens that are the same age, maybe a few weeks younger, that I got from a friend who was needing new homes for hers. They were always picked on, a bit but were fine since I let them free range during the day and they could easily run away. But I have a trip coming up and need to keep them all locked into their coop/run while I’m gone. I experimented this morning and there was quite a bit of picking. Two or three of my original hens constantly picked on the other four, keeping them away from the food and water. When I saw one pull out several feathers, I finally let them out to run free. My question is, if I leave them be and just make sure no one is seriously injured, is there a chance they may eventually work things out? I’ve had chickens before, but never had to integrate two flocks.
