i have tried suggestions but none have worked so far. I am now trying the allow single bird to free range daily, while keeping flock contained in run. The single bird has started to "own" her range by chasing away the squirrles repeatedly, as well as any other bird (I just hope this bird is a pullet and not a roo), she is about 14 weeks old. I am hoping that in a few weeks, I will have had everyone free ranging together and just let her go to bed with the big girls. Any suggestions about this plan is very welcome because I running out of time and ideas for integration. She has been bloodied several times now and I have removed her accordingly. So this is kinda my last hope for success.
