Final candling tonight, lockdown in the morning! Tossed 4 more eggs (mostly the ones I wasn't sure of on day 10, plus the cracked egg was a quitter). Total of 12 eggs left for lock down. I wasn't sure of two of them, but I left them in just drawing a little question mark on the shells.
I feel like I may have some early and some later hatchers due to the size difference inside some of the eggs. Some of the eggs look mostly filled and others have significantly more room but look healthy otherwise (can see movement, etc). What do I do if a few hatch on day 19 and the others aren't ready until a day or two later. It's my understanding that I shouldn't open the incubator until all have hatched, but I also don't want to leave hatched chickies in there for days while waiting for the other eggs. Is it normal to have different development rates like that?
Since I'm a first timer, can someone please confirm my plan for lockdown tomorrow morning?
Remove egg turner, fill water reservoirs fully, add a paper towel on top of the mesh rack (to help with clean up), replace eggs and lid. Fan should stay on, heat should be ~99.5, vents open, don't open lid until hatching is done.
