I brought a hen in that was getting picked on about a month ago. I gave her a bath last week but didn't see anything on her then. She has been in the house the entire time but last night I noticed in her cage after she had been picking at her tail feathers little red bugs crawling around. Worried they could have gotten in the carpet in that room too..treated her with revolution for cats. Read on another site it works and is not as dangerous as frontline. Just not sure which mite it is..not a bad infestation hen seems healthy and laying good too..
