Hi all, I have had two older laying hens for a year and have never had a single issue so I don't quite now what is happening. Yesterday, I brought home a 20-week old Silkie hen. I realized today she has one eye completely crusted shut, and she has mites on her head. The part of the feather shaft nearest her skin on her head is thick and white. I gently wiped across the eye with a warm wet washcloth and it loosened some but did not open. While holding her, she opened her mouth slightly each time she took a breath. She is not laboring to breathe, and she is relatively active and calm. She has eaten some of the layer pellets I offered since she has been home, but not a whole lot. (Of course, I could just be judging wrong, since I have two other hens who eat a TON of food and are very grouchy.) What could this be? And what can I do to help her out with the eye and the mites?
