No apparent reason why. He was fine yesterday, crowing, eating, "courting" the girls. He appeared fine last night when I shut them up in the coop. I did notice some mild frostbite on his comb last night and told hubby that I was going to have to google what to do about it. This morning when I went out to open the coop around 7:30am he was laying dead on the floor under his spot on the roost. I don't think he had been gone too long cause he wasn't stiff, but he was cold so long enough. Also, when I went back out at lunch to bury him I noticed his neck was broken....very floppy. Don't know he dead on the roost and that happened in the fall from his roost or if he fell from the roost some how and i He hit something on the way down. I'm puzzled. He is a (was a Delacauna ) 25 weeks old. He hasn't shown any signs of illness (other than the mild frostbite). Do healthy chickens just drop dead? An necropsy was out of the question today as the only place that does them is an hour away and I couldn't get him there today and they told me that even if I overnighted him to them they wouldn't get to him until Monday and that it would be too late then. I know no one can give me a solid answer, but any thoughts and ideas even would be appreciated.
