I have 2 silkie hens and 1 silkie rooster and 1 frizzle rooster. One of my hens is being picked on. One of her eyes is closed and the other is watery. I separated her from the rest. Is there any thing else I should do? Are there chicken antibiotic drops? Why are they picking on her? I am planning on pairing 1 hen and 1 rooster but think I should wait until she's better. Are they going to start picking on my healthy hen now that that one is gone? It's so sad.
