I have a beautiful rooster I've had a year he was a gift I don't know his age no other rooster around about 2 weeks ago stopped crowing stopped getting on perch and hanging out with his girls I assumed mited did a huge clean of coop have been treating with nutridrench and vetrx his comb is brighter but he's still not crowing I've been treating about 11 days have checked for impacted crop don't believe that is it he hardly makes any noise at all and stays alone

Welcome to BYC. Have you taken him off the roost at night when he was sleeping to look at the skin on his body for mites or the mite droppings? Have you had mites before? Or seen any signs? How do his eyes look? Is there any drainage from his eyes or nostrils, cough, sneeze, or any labored breathing? Is his crop emptying by early morning? Is he eating and drinking okay?
