A big air bubble?

I don’t know the humidity as it doesn’t show up on the incubator but the temp is around 37 to 38 I’ll send a photo when I get back.

that's the air cell, this egg seems to be losing more moisture than the others, if theirs are smaller.
Could we see a photo of one of the other eggs candled? Day 15 yes? Would be interesting to see how different the air cells are. What is your humidity and temp?

is the smaller one

That is the smaller one

it'll definitely help to have one, I got mine on amazon and it worked brilliantly! It was only about £5.
It would definitely help to see one of the other eggs, it would give us an idea of the current humidity and whether or not it's too low

I have got one if helps a lot the temp was incorrect and the humidity was really low

I actually cant see any veins, I assume you can see them, and movement, in real life? Often it doesnt show up on camera!

Temp being a bit low will slow development, so expect a slightly late hatch, at least now you can know so that you can work on getting the humidity up and everything!

No there isn’t any

No there isn’t any

Do you see any movement from the embryo?
If you cant see any movement or veins, could you post another picture of candling the egg in a very dark room, and remind me what day it is on
