No idea why or how that would happen unless there was gas in the egg, and gas comes from decomposition. But smell comes with that. Dunno, if there are only a few days left, leave it in and wait?
for the ones that didn't make it, but you did good!!! Go sit with your new babies for a bit, it'll help you feel better...
