I'm introducing my four 8.5 week old chicks to the three hens this week and wondering how long it usually takes for them to establish the new pecking order. I've had the hens for nearly one year now and they seemed like such docile ladies until I introduced the chicks. Now they seem like total bullies! All are inside a large common run, but each has their own Eglu coop with attached run, too. I put the 4 chicks outside about 2 weeks ago so the hens and chicks could get used to each other through the wire. The hens get their run door opened up every day so they can roam around inside the large, common run. This is the second day I opened up the chick's run door so they can come out, too. The hens are ganging up on them and chasing the chicks around and even keeping the chicks away from their (separate) food and water containers. How long does this intro process take?
