My rooster (over 1 year old) has been incredibly lethargic for the past 6 days. He just lays there head drooped down, eyes closed. Only opens his eyes if someone approaches him. I checked for mites between feathers and didnt see any. There are no scaly leg mites. He doesnt cough or sneeze. What do i do? I've been giving him electrolytes for the past 6 days and there has been no change in his condition
