I havent a clue about deworming my chickens so I have some questions.... How old should your chickens be before deworming? How often should you deworm? What do you use to deworm? Can you still eat the chickens eggs while deworming? Thanks! EDITED TO ADD: I just thought of some other questions... Do you have to deworm your chickens? and What is the worst case sonario if you dont deworm? Sorry about all the questions.
