Ok y'all! Yes I am live in Kentucky. I am a newbie to chicken raising just going on my 3rd year. My neighbor (we call him Chicken Bob) has raised chickens for at least 10 years along with goats. He told us to use food grade DE in our feed and sprinkled in our coop to prevent mites and internal worms. I have seen so much controversy about this. I would like some expert advice. Thank you!
