Lice normally like to hide around the butt area because of the moisture. In extreme cases, they will also be in the ears and under the wings. To check around the butt you will need to pick up the chicken and hold both legs with one hand. Turn the chicken over and pull back the feathers around the butt. If the chicken has lice you will see them moving.
Treatment: You will need to treat all areas on your chicken that have lice. You should also treat roost poles and the ground area. You can use “Seven” which is a garden/pet dusting powder or you can use Diatomaceous Earth for a more eco-friendly way. You should treat your chickens every 30 days for 3 months.
Chicken lice are not the same as human lice and will not stay on you. To remove any that may have gotten on you, take a hot shower after treating your chickens.
