Red Mite are small mites that live in the chicken house and come out at night to feed. They are mites, otherwise known as 'ecto parasites' that live in cracks and crevices in your hen house, coming out at night to hop onto your birds for a blood feed. They are a real problem that needs dealing with as soon as you notice them. Hens will become anaemic, stop laying and eventually die if the coop is left untreated. Please see our Red Mite section for more information as these really are silent killers!
