Lock down Tuesday 8 am 😁 I swear I saw speckled brown egg 'breathing' like chick was moving around inside. Circled eggs are still week(s) away

You may find the younger eggs hatch early because they can hear the older eggs getting ready to hatch and this speeds up the metabolism of any eggs lagging behind. This article goes into depth about this subject:

The member @MGG had two sets of duck eggs incubating. The two groups were 10 days apart and the younger ones hatched within 2-3 days of the older eggs starting to hatch.

I just had quail do this again last week! They were 9 days apart. It's so insane! OP, I agree. They very well could hatch together.
