A couple days ago, one of my roos started sneezing occasionally. He seemed fine, otherwise. Now one of my pullets is acting very strange and sneezing (Well, I assume it's sneezing. Maybe she's coughing). First off, she was still roosting when I came in. This might not be related but it struck me as odd since she's usually one of the first to get out and she's had over an hour to do it. Next, her beak is open and she looks distressed. She keeps on shutting her eyes, but while they're open they look very wide. And of course, she's sneezing. It's a lot more frequent and stronger-looking than what my roo was doing. She also seems a bit unresponsive. I showed her some of her favorite treats and she didn't appear to notice. Is this some sort of respiratory illness? I took her out of the coop in case it was caused by dust, but do I need to separate her and the roo from the flock? Please help! UPDATE: I just went to check on her. She had knocked over her water but there was a small amount of bloody discharge in there, though I'm not sure where it's from.
