I have recently added a coop extension. I extended my run and put a second coop on the other end. I can have one large run with a coop on each end or close it off and have 2 separate runs and coops. The extension will serve as a grow out pen or breeding pen ect. I purchased 12 new chicks last month. Unexpectedly, I had to take chick of mixed ages. I got 7 purebred Ameraucanas about 6 weeks old and 3 CCL and 2 Ameraucanas day old to 2 weeks. I kept them in two separate brooders respectively. After quarentine I introduced the 12 at the same time to the grow out pen (as described above attached to my main coop). The 2 Ameraucanas from the younger group immediately intergrated and attached themselves to the older Ameraucanas. The 3 CCLs stay completely separate and get picked on. They have been together for a week now with no major fights or injury. As far as safety they all seem fine. The thing is the 3 CCLs just stay in the coop while the Ameraucanas go all over including the run. I had 2 feeders and a waterer in the run. I moved one feeder in the coop and added a waterer to the coop because the CCLs never come out. They seem happy and healthy and there is plenty of room. Did I do the right thing or should I put the feeder and waterer back in the run? Am I encouraging separation? One of the CCLs is tiny so I wanted her to have plenty of access to eat so she can catch up!
