Day 24 float test should i help

Would you mind trying to calibrate your thermometers (or at least one of the main ones you use) just to satisfy our curiosity? It's pretty easy. Make an ice water slushy (small amount of water+ice+blender=slush) and pop the thermometer in. Give it 3 minutes and see what it reads.

It may not matter now, but could matter in the future.

EDIT: Another thing to think about is if your room temperature fluctuated, and your incubators thermostat couldn't keep up. It does happen to people.

It is reading 30

Can you take a candle your egg and mark the air cell, then post a picture of it?

OK! Well this is likely your problem. Your thermometer is reading 2 degrees lower than it should, so your incubator has really been sitting at 97.5 degrees instead of 99.5. This will create a late hatch and often time results in improper growth. The good news is, next time you incubate, you can calibrate beforehand and prevent this problem.

One side you can't see anything and the other the air sac looks like it has started kinda peeling off the side of the egg and going all the way to the bottom tip

I've never seen an air cell draw that far down.
are you positive its the air cell, or just clear liquidy area?

And no, no veins around the first one, it hatched that day. It was under a broody and i was checking it because others had hatched.

It is reading 30

If the sensor was touching the ice, it could read a bit low

Great idea!

Do you have one of those Braun ear thermometers? If so, measure the shell temp of some eggs. Be sure to measure about midway between the fat end and the pointy end, and not where the air cell is.

I only have cheap head thermometer that tells me I'm pretty much dead ice cold most of the time so it's definitely not correct.
