Menopon gallinae, commonly known as the chicken louse, is a type of parasite that infests poultry and can cause a range of health problems. There are several synonyms for this species, including Menacanthus stramineus, Menacanthus cornutus, and Goniocotes gallinae. These lice can be found on the feathers and skin of chickens, as well as on other types of birds, and they feed on blood and skin debris. Infestations can lead to skin irritation, feather damage, and reduced egg production. Effective treatment options include insecticides and regular cleaning of hen houses and coops to prevent re-infestation.
