I went out to lock everyone up for the night and our 7mo old silkie cockerel was hanging his head and not lifting it at all. He was fine yesterday and last night had his head down when I saw him on his roost. He's been eating and drinking the same, but I didn't notice anything today since I got a little busy. He was crowing earlier in the day though. Ideas, suggestions? I'm off to the store so I'll pick up some vitamins just in case.
