Hello everyone
I'm not very experienced with the process of incubation, I wanna know whether the air chamber size and the look of the egg is OK for day 7

Anyone please?

The first one looks good for day 7. The second one looks more like day 10-14. Can you feel the second one moving? Can you take a photo of it from a different angle incase that is all it is (which I suspect).

Thank you
Actually the second egg has a dark shell and it's also my bad photography, could you please tell me whether the air cell in the second pic is ok for day 7?

It looks perfectly fine for day 7 and the development I can see is good too. If the shell is thicker that would explain it.
