My banty cochin, Tribble, is constantly infested with mites. Today I picked her up and saw that the feathers of her rump were COVERED with mites. They looked like dirt on her, there were sooo many. My big girls don't have mites (or not many, anyway), just Tribble. It's disgusting. I treat her with Sevin Dust once a month or so. I'm so sick of it. She's a sweet little bird but her feathered feet and small stature have been causing a constant battle with mites. We decided not to get silkies for this reason, in case they have the same issues. Our clean-footed/tall birds haven't had nearly the issue that the feather-footed bantam has. It stinks! I'm SO sick of it!!
