My serama is sick. His eye is swollen and I cannot tell if its puss or his eyeball I am so worried have been treating him with duramycin-10 its not working please help don't know what to do or what it is. All I know is it is contagious and my other birds are starting to get it. I also did some compresses to see if I could soften the yellow what I think might be puss and it is still hard. I need help please. Also his comb is swollen and the other eye is watering.
