I have one hen left after a terrible attack on my flock by a neighbors dog. She survived (barely) and is traumatized. I thought bringing in pullets to start a new flock so she wasn’t solo was a good idea. They’re 11-13 weeks. I let them range together after 5 days of isolation in a coop/run in the middle of the yard. The hen pecks at the pullets and chases them. It’s going to get super cold soon and the coop I keep the big hen in is the best coop. The ones the pullets are in is one of those mobile coops that are flimsy. I was supposed to be getting older birds but when I got to the farm to pick them up the owner told me she made a mistake and they’re younger…anyhow- how do I get the chicks to use thebig coop? How do I get the hen to share the big coop- she floats her wings when I put a pullet in the coop. They all free range during the day and go to the coop to sleep. Do I swap coops between hen and pullets for the night? Help!
