Hi. Henny Penny has a dirty butt. It's not pasty,but dirty looking. I see a smear of feces on the wall of the nest box, but only that. None of her poops look abnormal. I dosed them all with wazine and plan to do safeguard in case it's a kind of worm. Could it be lice? I don't see the q-tip thing at all, just looks like that area got wet and is now dirty. She eats layer pellets and is out free ranging all day. Sorry to say, I haven't been attentive the last month or so, DH was in hospital & I pretty much came home to do basics and went back to stay with him. I will do a thorough cleaning/sanitizing of the coop this weekend and probably sevin dust the crevices. Anything else I should do? Thanks.
