I recently got rid of all of my chickens except one old hen and one turkey hen because the fleas were torturing ME! I treated my chickens several times and the fleas would come back. Finally I got rid of the chickens, except Loretta and Gravy. I haven't seen fleas for quite a while and I'm ready to incubate again. My friend told me to put ashes in the chicken pen and that will keep fleas away. Has anyone else tried this?
