adjustment continues

The introduction of the new girls to the coop is not going well. Last Thursday during some supervised play time the big girls ran the little girls out of the coop and I found them huddled in the bushes in the back yard - safe from the big chickens and the dog. It took me hours to get them back in the coop. Today I opened the little girls coop and let them out and the big girls immediately started pecking them and cornered Sunny Jr - then pinned her between a 2x4 and the ground. I pretty much thought they had killed her. I was able to shoo them away and pull her out - she is fine. BUT back in the little coop the little girls went. Sigh. I will get some more chicken wire today to reinforce the bigger area so the little girls cant escape again. This weekend I will add a roost bar in the coop so the little girls have a spot of their own - if they ever can co-exist the the big girls!!
