I went out to close the coop this evening and was one hen short. I found my Bianca (3y/o NH) dead in the sunroom (old truck topper). She had a bluish comb and was extremely bloated -- so much so that I had to struggle to get both legs in one hand. I palpated her abdomen and it was not hard; it felt more like a really full water balloon. I have her on ice for the weekend; I'll try to get her to (which agency??) on Monday. Until then, I'm worried about my other chickens. Does this sound like something horrible and contagious?
