Hello. So long story short, about 6 weeks ago a couple of my chickens were attacked by a dog. Since then they have all been separated in separate cages inside of the coop and have healed up nicely for the most part. About a week ago I was able to finally release one of the hens back into the flock and everyone was fine. Then today I tried to release a second one but a fight broke out and had to be separated again. How should I go about handling this? Also this hen is really struggling to grow her feathers back after the attack and some seem to be growing in sideways or crooked. Do I have to wait til all her feathers are back before being released with the others if that’s even possible at this point with how “aggressive” she’s being to the others. Also a couple days ago it looked like a blood bath in her cage and she had dried blood all over her. Didn’t know what it was from til later that day I spotted her trying to fight one of the hens through her cage which is probably how she got hurt. Please help.
