Well, everyone seemed normal and healthy. The bodies weren't pecked. There were 22 chicks living on the floor of a horse stall penned into a 4'x4' area. I had chickens until recently that sometimes went in there. I wasn't feeding medicated starter (but will probably start). I haven't noticed bloody poops, but then again, the area has a lot of stuff in it so I haven't noticed much poop at all. The second one I found was still warm when I found her and had looked fine an hour earlier. Heart attack??? I don't know.
