I understand that this might not be the best first post, but I had to google a chicken forum and join it fast. My rooster seemed fine until last night, when he showed himself to be slow, sort of lethargic. When I tried to give him water this morning he kept vomiting it all out. Just the water. It seems food doesn't come out, or he can't vomit it, I don't know. His comb has also been droopy for maybe a week now. I'm in a panic and don't know what to do. The vet is closed for another three and a half hours. Please help.
