Fact: a chick that developed properly has absorbed the yolk and has nutrition onboard to support it for up to three days. That is why hatcheries can hatch chicks, leave them in to dry, pull the trays, pack the boxes, and ship them out for delivery and have them arrive alive up to 3 days later.
Fact: a chick still appreciates a cool drink of water once it has hatched and dried and rested.
Once MOST of the chicks have hatched and dried and fluffed and no eggs have an external pip, you can snatch the dry chicks out and place them in the brooder. This can be in 8 hours, 12 hours, 24 hours, or more. Getting the humidity back up for the unhatched is critical.
If the humidity in your hatcher is very high, 75-80%+, you can pull them one or two at a time as they dry and become active.
The eggs getting rolled doesn't affect the chicks about to hatch. They are in position and are not going to be affected by rolling, unless they are too wet, or if it is a staggered hatch.
