I've been wondering this since my hatch last week. The chick hatched out last of the bunch, hatched by itself with no intervention, but wasn't 'right'. It died that night. Just seemed premature, it never opened its eyes (must have had them, but never opened them), never got its feet, still had the cord and a red mass attached, and basically just laid there and breathed. So I'm curious, if it was strong enough to hatch, why didn't it live? Was it actually premature, as it appeared?
