My rooster won't eat, drink, move, or do anything. He is having trouble breathing and his tail is tucked. His poop is lite yellow and lime green. We have been giving him apple cider vinegar water with electrolytes and silver water. He us 1 of 2 left from my original flock of 8 and we need him for our new hens that are coming for meat chicks. How can we figure out what he has?!
