Lice
Lice are often found on hens that are debilitated or unwell, and live their entire lives on the body of the host chicken; adult lice shun sunlight and will quickly scatter when feathers are parted. They cannot spread to humans or other species.

Depluming Mite
The depluming mite (knemidocoptes gallinae) can infect most backyard fowl including chickens, ducks and geese. The mite burrows into the feather shafts and the skin surrounding the feathers.
Northern Fowl Mite
The Northern Fowl Mite’s entire life cycle is spent on the host where it feeds on blood and is a source of irritation to the bird. Eggs are laid in masses at the base of the feathers, usually in the vent area.
