Last spring I successfully introduce 3, 9 week-old barred rocks to and white rock hen of unknown age. All was great until we lost one of the BR to a dog over the winter. We replaced her with an Easter Egger and Buff Orpington who are now 12 weeks old. I knew the introduction would be harder, but I quickly becoming discouraged!!! The 12 week-olds have been housed next to the big girls for over a month. They have been using the run when the hens are free ranging for even longer. When they free range together, it's not too bad. The BRs chase the pullets occasionally, but nothing serious. Everyone in the run together is a completely different story. Our White Rock is doing what she did when the BRs were new. A quick peck, no big deal...she is also the top hen. The 2 BRs just don't want to let up on the little girls though. The only time it's peaceful in the run is if the 2 little girls hide under the old Christmas tree I still have in there. Today I finally took the 2 Barred Rocks (I call them the evil twins) and put them in the pullet's quarters (it's a 4x4 coop that's attached to the coop they have been using. They spent the rest of the afternoon there and are spending the night there as well. The pullets stayed with the White Rock and are roosting in with her (with a little encouragement from me). Does anyone think this will work? The barred rocks were very unhappy, they could still see the other 3 and were very vocal until the sun went down. Even the white rock seemed out of sorts. I am just hoping I haven't made things worse! I guess I am hoping to hear some successful integration stories. Our run isn't huge (64 sq. feet)...am I asking too much for these 5 to get along?
