I've got myself in a bit of a quandary. My almost three year old rooster, Truffle, is having some breathing difficulties. He's gotten weak and lethargic, his tail is drooping, and he doesn't eat or drink very much. The end of his comb is a dark purple/blue, which I think is due to a lack of oxygen. He's not panting/choking/rattling/coughing etc. He only gasps when he's super stressed. For the most part, it just seems like his body 'inflates' more than it should. It's like he's breathing deeper with each breath, even if he's still silent. No gunky eyes or nose, but is poop is watery green with lots of urates. My biggest concern is that his father, a Phoenix, had similar lifelong breathing problems. The vet could never find anything 'wrong' with the old boy, and it eventually killed him. Could Truffle's problems be the result of bad genes? There's not much to go on besides lethargy, green poop, and deep, silent breathing. Most respiratory diseases I've looked up have some other component, like discharge or strange noises. He's got none of that. Is this something curable, or did Truffle get the short end of the gene stick?
