I agree with the others--find something else to do. I try to find things that take me well away from the eggs for hours at a time. It's so exciting to return with the thought that maybe there will be something to see when I get back... of course, it's heartbreaking when there's not! Makes me want to bite my fingernails to the quick for vexation!
It really does seem like FOREVER when you're watching. I recently hatched a batch of quail--they are 18 days in incubation, and they go from rocking to hatching in less than 24 hours. Their zipping takes about ten minutes. Then I hatched a batch of ducks, which is what I'm used to, but after the quail, I thought I would DIE of impatience. It takes them pretty much 48 hours from pip to hatch, but because I had gotten used to how quickly the quail hatched, I kept thinking they needed help because they were taking so drattedly LONG. Aagghhh! I finally had to gather up my kids and go to the park for several hours to keep from pulling all the eggs out and breaking them open myself!
So... I'm with you. It's SOOOO hard the waiting. Go find something to do!
