How frustrating when clucking over eggs for a month then finally see the beak emerge only to watch it die hours later. I am not sure what happened other than it piped at the mid-line instead of toward the top. I thought perhaps it was malpositioned but hoped that it would work itself out. It only lived about 9 hours after it's air hole appeared ;( I peeled some of it back to see if I could get an idea of what went wrong. It appears that it's butt was in the large end and head was mid way down with right wing over it's head which is, I believe, where the wing should be but not sure about head being below it's butt. Hoping the next one will be ok.
