I could really use some help here! Last night we were dusting our chickens for lice/mites when we found one of our girls' preen gland looking like this. It was nasty. Do they get infected or could something else be going on here? She's our biggest, fluffiest girl, a Buff Orpington, so it was hard to even find her gland. Then I felt bad when we found it, because I hadn't found it earlier. I'm not sure how long it had been like that. She hasn't shown any signs of feeling bad or anything. Any help or advice is greatly appreciated!
