Maybe so, or someone gave them a big shake-up. I have 3 that are suspect, but it's either all or none with my turning trays, so leaving them to their fate to a degree. It's really hard to see through my Orpington eggs - they're only light brown, but the shells are quite thick.
Do you guys rearrange the order of your eggs in the incubator so they don't spend the entire time in the same temp zones, and if so, how often?
My Bator tends to fluctuate a degree or two in some places. I have a central probe and a cold spot probe, there's one hot corner(might be due to my lizard's t5 controller in the same cubby space) and I've not put any eggs near that side.
Do you think it'd give better hatch results? My Bator has a built in candler, which actually kinda works for the white eggs. Still only day 1 so way too early to see who's taking and who isnt.
