Rooster appeared healthy a couple hours ago but now found him dead in the coop. Feathers look ruffled and messy so thought maybe he could have fought to the death with our other rooster but these 2 roosters grew up together and we have seen no sign of aggressive fighting between them and the other rooster looks perfectly normal. There are cats in the area and we have seen cats pounce at the chickens before but have never actually seen them fight let alone kill the chickens. I don't see any blood. Anyway, my question is with a chicken dead from unknown causes should I consider it potentially diseased and just bury it or should I still think of it as safe to butcher and eat it?
