No pip - Past hatch date

[cluckinaround207]

All of our eggs hatched between Friday and late Saturday night (it is Monday). Two remain, and one I am not sure if there is any movement because it is a dark green egg, but the other is still moving. It has not pipped, but movement is slowing down. I don't want to do nothing, but I don't want to cause it harm. Do I risk this and try to save this chick and open it, or leave it and risk losing it anyway?

Typically any eggs left after the first big hatching event won’t be hatching on their own. Yes there may be one or two who manage but IME they usually need help or are already gone. Often times they are slow to hatch for a reason too, such as a deformity or bad positioning so be prepared for that.

I would help the remaining chicks. Start by chipping away at the air cell end of the egg. I use a sharp screw to drill a hole in first, then see what is going on. There’s an article on here somewhere that explains how to do an assisted hatch.
