When I came home from the weekend my 2 month old rooster was acting different. His wing was droopy, not great balance, not moving around much and hasn’t crowed all day I have brought him inside to Separate him from the others Incase it’s a contagious disease. He will literally stumble over his drooping wing. I don’t know where to start to get him feeling better or to figure out what’s wrong with him! I was going to start by adding vitamins!
