My Light Brahma rooster, about 8 months old, has suddenly developed droopy wings. I saw my geese doing this when we inadvertently gave them too much protein but I have not ever seen a chicken do this. They just kinda drag the ground. He seems fine. Eating and drinking. But he can't get his wings folded and all tucked up tight like they're supposed to be. He is in isolation right now because the other roosters are taking advantage of him. Is there a vitamin deficiency? Nutrition issue? What the heck?
