I have an 8 month old silkie/leghorn boy that went downhill very quickly. He was fine this morning. I get home from work and noticed him standing near my blind girl who had apparently escaped her pen. I scoop up the blind girl get her settled and didn't really notice anything with him. So I go about doing their feed and water and notice one of his favorite hens was not with her chicks and find her laying with him under a bush. He was panting at that time and thought he was hot and gave them their food and water by the bush. Going ahead, he did come into the coop but was not acting himself at all. I get him to check him out and he is lethargic and his eyes are closed. He has drank a few sips of water here and there but that is decreasing now also. I put vitamins and electrolytes and an antibiotic in his water just in case. He has absolutely no visible signs of injury. He did poo and that was normal color but maybe on the dry side. He sounds stuffy now, like someone with a stuffy nose. He has this really strange large comb and I really can't see his nostrils to see if they are blocked or anything but I have not seen any discharge on his face. He has not eaten at all. I am at a loss as to what might be wrong and what to do for him. I did bring him in the house and offer water but now he really isn't taking that either. When I had lifted him up, a sound sort of like a burp came from him. I do have other roos but there are no injuries on him whatsoever so I don't think anyone did anything too him. I thought at first he might have gotten hurt protecting the blind girl from the other boys or something?? I suppose he could have found something and ate what he shouldn't have but I have no idea what it might had been if he did because I don't know what it could have been. He is going downhill fast whatever it is. He is one of my favorite roos and helps take care of the chicks. I am so upset right now because I don't know what to do for him!
