Is it possible to add just one hen to a small flock? She is smaller and younger and these past few days I have been with them the whole time. The older pullets are still not accepting her and it seems like everything I have read talks about adding more than one and of the same age. The chickens are free range backyard chickens they have chased her off into the garden a couple times and this morning I put her in the run with a more docile chicken and they did fine but when I added another chicken a few hours later she was being bullied but I didnt let it escalate at all. Any suggestions...its only been two days btw.
