Silkie Hatching Eggs! Questions

[Chaoth]

My silkie hen (Choji) is currently hatching eggs! 1 chick came out yesterday, and another was fresh out of the egg this morning (haven't gotten a pic of the second one yet). Both parents were pure white when we got them, but the papa turned into a splash variant with brown on his head.. both chicks are grey so far! Isn't that neat?

This is my first time hatching chicks, and I realized mama had some of the eggs not fully under her this morning so they were getting really cold.. should I be concerned? Is she rejecting them? For context, she's never hatched chicks before this and she has 8 eggs under her (including the chicks). I think they were 3 days overdue when they started hatching/pipping yesterday.. should I just leave them alone?
Also, will mama leave the nest while the chicks are hatching still?

So far the chicks look really healthy, and I've been making sure mama goes out once a day before now ((never forcing her)). I'm hopeful that more than two of the eight hatch, but I've only been hearing those two chirping so far.

Thank you!

She most likely didn't notice they weren't under her since this is a first time, just tuck them back in and hope for the best.

Alright! I did push it back in a bit when I saw it, but I'm not sure how long it's been cold. Thank you!

Update: 5/8 of the eggs made it! 2 eggs were not fertile and 1 sadly passed away because of the cold during night.
The mama is pure white, papa is a splash variant.. can that make a blue variant?? All of the babies are varying shades of grey. Thanks!
