I'm so excited tonight - by magic, it seems like my two 12-week BRs are integrated with my four other girls (a variety of breeds, about 19 weeks). They're all in the coop together tonight, and I'm hoping it will all be peaceful tomorrow when I go to let them out. I had them separated in their own pen and overnight box for a few weeks, and I've gradually been letting them mingle together in the evenings, and tonight it just seemed to all come together. Fingers crossed that tomorrow morning everyone is well and happy in the henhouse!!
