I am on the brink on a total meltdown right now. I have got a 1-year-old buff orpington with infectious coryza. I know it is coryza because her face is swollen, her eyes and nose gunky, and she smells like she is dead. I treated her with tylan 50 injections for 4 days and she is still very sick. I came home tonight and her eyes and nose are very gunky. I cleaned it with hot water and Vet RX. There is no point in quarintining her. She has already been around the other chickens for too long. She looks SO BAD (like a chicken that has been dead for a couple of days). She has lost so much weight already. My other buff and one of my cochins are also showing symptoms too. I have 7 ten week old chicks in a seperate coop and I am so scared that they are going to get sick too. I can't even let them out to play in the yard because I am scared of them getting infected. The coop that the little chicks are in was meant for all of the chickens and I had planned on having everybody moved in by now. The big chickens are still in the summer coop and they are cold! I just don't know what to do. I know that this seems like senseless rambling and that it makes no sense. I'm sorry. Please give me some other advise. I CAN'T CULL!! Please don't suggest it. I culled once before and I just can't do it ever again. I forgot to mention that the 2 buffs are molting right now. Could this be the reason for the weight loss? Could the stress from the molting be what brought on the Coryza? I know that they have been exposed to it and it was probably dormant and that stress sometimes brings illnesses out. Could this have been the reason?
