The last batch of eggs I incubated were SEVERELY staggered. My first batch had 10 eggs all due the same day. Then I added 3 more eggs over the next 3 days. So, once my first batch hatched, there was a 3 day span for those other 3 to hatch (if that makes sense, after lockdown started for the first eggs I didn't open the incubator for 7 days). However, a week after I set those I put 20 more eggs in. So, that first batches lockdown prevented me from turning that last batch for their entire last week of incubation.
That second set of eggs, the ones I didn't turn for that last week whole week (which I've read is when turning is most important) hatched better than the first batch which I turned 3x's a day for 18 days. I don't use my incubator very often since I have lots of broodies to do that job, but I really think that if they're meant to hatch they will. I've read lots of posts where folks have temp spikes, the bator gets turned off, crazy hatching methods are used, ect and their chicks/ducklings/poults made it. They're alot more resilient than we give them credit for! Good luck!
