can a chick hatch after opening a bit of the egg?

I'm sorry to be mean but you are confusing me

You aren't being mean. I was just wondering how long she has been sitting on the eggs under her now.
It only takes 21 days for a chicken egg to hatch, so if those eggs have been under her for 27 days, I doubt they make it.

obviously nobody knows your setup so i am also just guessing but if this chicken lives with other hens and they had access to her nest/nistbox, there's a good chance they supplied her with additional eggs over time...

No the hen is in another coop in the basement and I went to candle the eggs I saw movement
