Foat test question - lockdown today

[MamaMarcy]

Since my staggered hatch has had so many power outages the past couple weeks, I figured I might just float test my 5 buckeye eggs. On candling, they all look "full" but not the usual movement I get at this stage. All have air cells where they should be.

So, all 5 passed the float test except one SANK (but still rocked from chick movement)

Should I be worried about this sinker? I'm stumped cause there's an air cell. Could the air cell be full of humidity instead of air? I did a dry incubation (40 or less) aside from higher humidity (60's) the past 3 days from another hatch.

Hmm. I wonder if it is humidity if I should PIP the blunt end to let the moisture out? (as in a tiny hole)

Opinions GREATLY appreciated

I did the float test on my eggs but had no movement in any of them. They all floated above the water...some more than others but still floated. Sorry, I know that isn't helpful. I am going to follow this.. hope someone who knows more about float testing will answer.
