I have a mite infested coop. I took out all of the old bedding, cleaned it thoroughly dusted it with permethrin powder as well as dusted all of my chickens with the powder. Since then they have all been on a broad spectrum de-wormer with the main ingredient being diatomaceous earth and i have read feeding this will help prevent mites. After all is said and done the chickens still have mites... hmph. Any hoo- while i am fighting this never ending battle between mites and men-because the mites just aren't enough- I have another problem developing. A VERY sick rooster. He is very lethargic, droopy, he is limping, has a pale comb and has not been drinking, all of this along with dramatic weight loss :~( I brought him inside today and put him on a heating pad- he felt cold to me. I gave him fresh water with antibiotics. I syringe fed him for a while, than he started drinking and eating on his own. I dusted him with DE and sprinkled a bit on his food. What i want to know is can mites cause this kind of sickness? Annnnd what else can i do for my rooster? Annnnnnnd what can i do for the mite infested coop? Any good ideas or remedies that have worked for you? Please help! I love this rooster to death.
