My chicken is slowly dying. Last week I noticed her cheek was getting pale and her breathing was getting labored. Now her face has lost all of it's color and her wing are droopy and her breathing is getting bad. I thought in was mites so I dusted her and I have given her avia charger in her water. I don't see any mites but what would cause the blood lose on her face? I lost a chicken in the middle of winter with the same problems. And that chicken had mites crawling on her when she was dying. They (mites)even bit me. I've cleaned the coops and dusted everything, about 2 months ago when I lost the first chicken. My chicken died.
