I noticed a few days ago the roo seemed to be sneezing. I didn't think anything of it, thought was occasional normal sneeze. Until tonight, when I happened to be putting them away. I swear I heard him laboring or wheezing type of breathing. Any ideas and what do I do? If I isolate him, what do I use? Our coop is small. Oh, and I'm pretty sure he has some starting frostbite on his comb. I only say that because I noticed today it's on waddles as well. We bought our coop from a gal in town, she had no issues with any of this.
