I bought 3 Calico Cochin roosters thinking 2 of them were hens but all were roosters. Anyway I got them home and immediately began seeing sneezing and "coughing" if you can call it that. I think they have a respiratory infection and I can treat that. But I also think one of them has a touch of Coccidiosis which this is the second time I've had to treat my chickens for it. One of them is doing pretty bad. He's lethargic (has a lot of energy when you approach him though) and has some nasal discharge. Not much but it's there. I took him inside and cleaned off his beak because he had some stuff on it. Not all was the discharge from nostrils. I gave him some Corid in his mouth and he seemed like he was having trouble swallowing. So then I gave him water in an eyedropper and again, he looked like he had trouble swallowing. He was also making a soft noise repeatedly when he was running around. It looked as if he was dying which he wasn't. He's still fine. He is eating which was a surprise to me because I thought he wasn't. We put him a pet crate in a safe barn away from the others. When we put food in there, he immediately began eating which was the first time I've noticed him eat all day. Should I start VetRx? I was going to sell these roosters but that has been put on hold for now. One of my other chickens that I've had for over a month now, was "coughing" a week ago but I haven't heard it from her for a day or 2 now. I need to get them better so I can sell them because I have too many roosters.
