I had an incubator with a tray, so I could take the tray of eggs out. I think I left them up to 30 minutes, then put them back in the warm incubator. If you took off the lid, I suppose you could decrease the time to around 10 minutes or so, so the incubator would slowly get back up to temp. Also, I forgot to say but you do not start misting until the 4th day. It doesn't matter what time you do it, but I usually did mine in the late afternoon. Our humidity was 55%ish for normal incubation, and 70-80% for lockdown. Good luck!
