I had a 4 month old rooster and pullet in a separate pen from my 5 older pullets (5 months old). I free ranged them together for about a month and then moved the rooster and pullet into the big coop. All was well, no problems. About a month ago my head hen was hurt by my dog. I had to take her out of the coop. The next day the rooster and one of the older pullets fought. Her comb was bleeding. I believe she started it. At the time I thought she might be rooster but she has since started laying. I tried putting her back in, he immediately attacked her. I tried free ranging them together, he attacked her. The top hen is recovering so I tried putting the two hens together, they were pecking at each other and the head hen isn't strong enough yet. When the head hen completely recovers, is there any way to get them all back together.
