Hi! So I have 4 beautiful hens, but recently, my white leghorn was limping,so we took her in our house and let her recover. It has been 3 days since she had last seen her sisters. Well, today we let her back into the coop, but our very large hen, Brownie, pecked at her. I brushed it off, and then I let all of them into the garden to peck at some worms. All was fine, they were all happy. I thought that it was all fine, so I let all of them back into their coop, and left them there for an hour. When I went back out to feed them, I find my white leghorn laying on the ground, trying to take a dustbath. But, when i looked closer, the side of her head was all bloody! I thought that it was Brownie, and I took my white leghorn back inside to wash her. Right now, she's with me back inside the house, but I'm really worried about how to introduce her back to her group. Any suggestions?
