We have a chicken that was given to us and was told it was "wormy." We've been treating it with the diluted water that was recommended at the feed store and she rallied a bit, but she's not moving much, pecks a bit at food, and I had to clean out her eye that was crusted over and clean the other one that was getting a bit nasty. They were fine yesterday. Help! We know our chickens have mites and have been treating them for it, and diatomatous earth we mixed into their dirt bath helped some, the feed store gave us some sulfa for refractory mites, but it says not to use around pets. What should we do?
