How early to take off turner

[Oofies]

I have eggs in the same incubator that were put in on a Wed, Thurs, and Friday. That is the way they were shipped (I couldn't stand to wait to put them in once I got them...) I will be out of town until LATE the Sunday before they are scheduled to hatch.

Can I safely take them all off the turner on Sunday or should I take them all off on Friday am? Will that mess up the ones due to hatch on the following Friday?

How late/early can you stop turning eggs?

THANKS!!!
