Egg help info help

[Pigeonbeast]

[/IMG]Hi guys! Seems like my other 2 pigeons became a pair & the female layed an egg. So i went into the loft and noticed an egg on the ground near some hay. Ive heard that the parents or basically the female won't sit on the egg until she lays the second egg. Please look at the pictures ive uploaded. Can someone tell me what this small circle is inside the egg? Is it a chick or just something else? Thanks guys, help would be appreciated!
