This egg is one from the batch of shipped eggs that were under my broody. I think maybe that's why it's so far ahead of all the others. It's also the only shipped egg left, so that's why I am thinking of even trying to help it. Would hate for a fully formed chick to die internally pip'ed because it ran out of air. I think I will wait until morning to see if it's still moving and see if it hasn't already pip'ed externally itself.

Thanks guys. I have a weak stomach so I don't think I could do more than poke a hole for air.
