Side pip--should I worry?

[coloradowildflower]

This chick pipped about 4 hours ago and I have been watching the little beak in this window...the membrane seems still intact. Is this a cause for concern, or a normal progression?

Nope. Nothing to worry about. The air cell drew down that far right before hatch.

Thank you for the reply! By the way, Punky Brewster was my favorite show when I was a kid!

 

[Punkybrewster]

Haha. Thanks!

Just updating that her hatch went splendidly! She eventually broke that membrane after about 8 hours, then took another 12 hours to start zipping:

After that, she went ahead and zipped right around and hatched within an hour! Thank you for your reassurance. I'd never seen a side pip before!
