Incubating eggs

[chickencoop97]

Hello guys, I'm incubating 6 eggs for my first hatch and I candled them they are 10 days now. I noticed that one egg has an air sac smaller than all others. Can somebody post here how eggs should look when candled during incubation? Thanks a lot for the help.

Hmm. After seeing the pics I think some of 5/6 of the eggs are on day 19. And one is one day 7. Silly hen how'd this happen.. I'm using a broody hen for incubation thanks for the help

Depending on your ambient humidity, the air cell can be different.

Ah.. So it is possible that the eggs are not on day 19 and they're on some other day?

The air cell doesn't determine the day of incubation. The day of incubation and air cell determines if the humidity has been correct.

Rather than candle and worry about humidity. I weigh my eggs. They should lose 0.65% weight each day. Different eggs will lose at a different rate so by weighing the eggs I know if I need to raise or lower humidity.

i see. So if they are losing too much then I should raise the humidity then? How can I do this I'm using a broody hen.
