I have 4 hens and 3 ducks. All female except one duck, turned out to be a male- he is 13 mos. old. He chases a couple of the chickens ( the other 2 he was raised with) and was pulling on their feathers, etc...one chicken, my red Tanya ,fights back and now poor Sammy has a partially bald head and gunky eyes. What do I do for his eyes? He can see and I have rinsed them with saline. I am going to have to keep him separated for now....I really wish he had been a female, but I love him. He loves his 2 chickens, and the female ducks...but not the other 2, hens who fight him when he chases them. It is like Poultry West Side story! Any suggestions for his eye?
