So since my chickens and turkeys are destroying my garden i'm moving them to a different fenced area--the barn has dirt floor consisting of dirt and old goat poop. My concern is the meat chicken who is there right now developed mites and i think i've seen some fleas. Is that typical for old dry manure barns? I've been spreading diatomaceous earth. Would nematodes help? Also, is the only way to move them wait till night time and carry them one by one? Thank you.
