‘Mallophaga’. Lice are light sensitive and scurry away when the feathers are parted. Young lice are pin head size and white, while adult lice are usually a brown colour.
Areas to look for lice are under the wing, around the parsons nose and around the feathers below the cloaca. Lice are transmitted between birds by direct contact. There is no part of the life cycle away from the birds. Eggs hatch within a few days, and the eggs are usually visible in chronic infections as fans of eggs, particularly under the wing.
are also known as red, grey, and roost mites. They can live in the human home. They can also lead to anaemia, causing pale wattle and combs. Sometimes chickens will refuse to lay in nesting boxes infested with mites. They easily kill young chickens and broody hens. As they are nocturnal, you will not find them on your chickens during the day. Instead, during daylight hours, they hide in the nooks and crannies of your coop. Once laid, they grow to adulthood by day 10. They can live in a vacant chicken coop for up to 5 months. They use poultry as a mobile cafeteria and suck blood during the nights, so they are not usually visible during the day time. These poultry mites are pin sized.
