Not alot but a couple peeps, the ones last year were making noises before lockdown too. These are the only breed I've hatched get noisy so early. Its muffled but its definitely peeping. That's why I was considering lockdown at the beginning of tomorrow instead of the end just in case. The last thing I want is for someone to get squished in the turner.
If you hear peeping, then they have internally pipped and humidity should be raised immediately. Once they break that membrane, it can dry out quickly. I'd go ahead and lock down, no matter what the calendar says. I'd also candle and verify. jmho
Good luck!
