My rooster, BB King didn't crow this morning so I went out to check on him. He was bright eyed, but just didn't look himself. Took him out of the coop to sit on the stairs with him and he started puking a clear greenish kind of mucous looking fluid. Stood up tried to crow and fell over dead. What in the world? He was a 9 month old lavender Ameraucana and was fine yesterday. I'm just heartbroken.
