Ok. So last night I had noticed one of my eggs had a crack from the inside. Well today, a couple more have it as well.... I noticed when I candled the egg last night that it had a very weird shape air cell. And it WAS moving. This is my first hatch so i'm no sure if i should be concerned. I'm on day 23. This is not the best picture, my batteries died right after i clicked the picture but i think you can get the idea of the air cell. Please let me know if I should be concerned or wha I should expect with an air cell like this.
