I noticed yesterday that my little cockerel had what looked like discharge around his nostril but was actually just off coloured skin. Then tonight I did my check on them and decided to take a good look at him only to discover his other nostril no longer has an opening.. it wasn’t the biggest opening yesterday but now there’s basically nothing he can breath through. I did notice some clear wet discharge tonight around his nostrils and he had some bedding stuck to the other side. When he gets worked up and moving (flapping his wings for a few seconds) he starts to use his mouth to assist in breathing. I’m unsure if this is to do with his comb being so large or him maybe having an upper respiratory infection?? I added some photos to show the difference between his left nostril (first photo was from he 24th, second 25th) Thank you in advance for your help!
