I believe it will be ok.
Do not open the bator!
Sounds like with all the activity of the other chicks it will probably be rolled again to another position.
The pip facing down probably won't keep the little guy from zipping.
Will it still be able to hatch? Do I need to do something The other hatched chicks keep rollin' them over.
This is the reason I started hatching in egg cartons. Most of the time they'll still be fine, but I've had them get stuck in that position. I wouldn't open the bator tho unless it's the only egg that's left to hatch.
