I have some 14 week old pullets that I have kept in a small coop for five weeks. Their little coop has chicken wire and is placed up against my large coop that also has chicken wire. They have been there for five weeks in plain sight of each other. They have also been let out into the yard together but they never mingle. The little ones don't go too far from their coop. Last week we decided it was probably okay to move them in together. My husband moved them while it was dark and I thought all would be well. Later that day I noticed the pullets were huddling in a corner together. I also saw feathers from one of them strew throughout the coop so I knew the big girls were pecking. We moved them back into their little coop right away. It's been five weeks and it's getting stuffy in the little coop. When do you think I can safely move them into together? Do you have any tricks you can recommend to make the transition go smoother? We have two hens and four pullets. Thank you in advance. Any and all advice is appreciated!
