About a month ago I posted about a bantam chick with a swollen area around the oil gland on his butt. I thought it was getting better for a while, but it looks terrrible now. This is what it looked like when we first noticed it. Even worse, I have three other bantam chicks (about two months old) with similar symptoms. They have swollen places near their oil glands that look like the other one looked when I first noticed it. This these two, for instance, with their swollen and bare spots above their tail feathers. I called every vet in my area, but unfortunately, none of them will look at chickens. I have put hydrogen peroxide on the worst one, but I don't know what to do. The worst one has become lethargic, and pretty much just lays there all the time. Does anyone have any ideas? Do I need to just put it out of its misery?
