One of my rooster is very sick today. He is a pet bird and I want to help him, I just don't know what disease he has. He has had very watery eyes for a couple of weeks. They are not swollen or sore. The don't have bubbles in them. It looks like he is crying. He seems worse in the morning, and in the afternoon his eyes look almost normal. He seemed to be getting better. When I went to check on him this morning I was shocked to see lots of thick mucus dripping out of his beak. It look like what we get when we get a bad cold! Its a bit milky colour and transparent - and very thick like slime. The strange thing is he is not acting sick at all. He is not hunched up, he is still running about mating with the hens and crowing, flapping his wings and eating lots His breathing is normal, he is not coughing or sneezing or shaking his head. I can not understand it. Anyone know what this might be? All the other chickens and roosters are fine. I am so worried about him.
