Day 21 and no zipping

[Jaxx_]

It’s Day 21, one chick out of my 2 have piped but hasn’t started to zip at all. He’s been piped in the same spot since yesterday.. should I be worried?

Update.. it hatched

Hope the other one hatches for you...

Edited to add... If by chance it doesn't, I would suggest running to the feed store to get the little one some buddies to grow with, so it's not alone. Hatching more than just 2 eggs helps here.. But hopefully the second hatches and all is well
