What happened? I am on day 23+, have two eggs that moved during float test - no internal pips though and no chirping. I checked 7 eggs that I was pretty sure that had died. 3 had died earlier, but 4 looked like they were fully developed. Only one had pipped internally - and was wet...possibly drowning?. All the others (most in correct position) were shrink wrapped. I had had some early lockdown humidity issues.
I would be in the same boat as you though - still alive, late, no internal pip, and a history of potential shrink wrapping.
