Can newly hatched chicks survive with the two mama hens who hatched them out?

I have 5 banty english orpingtons who brooded together last year and raised the chick together. Then 4 of them went broody again and raised those chicks together. They are broody this year also in a group. Weird.

I guess bantam hens are notorious for brooding. The two chicks are doing awesome. Learning to eat and drink with mama and Peeking out sometimes.
There are still 2 viable eggs under them. I am pretty sure I put them in with them a few days late as I was worried only one chick would hatch. They are were flutters last night and showing the heart pulsing.
