Has anyone hatched a first laid egg?

[Project Blue]

On December 29th I found a dark green egg in the coop laid from either a Splash Ameracauna pullet, (not likely) or a half Ameracauna pullet almost certainly the layer. I'm not expecting it to be fertile as the rooster is also a first timer. He has grown out nicely but doesn't seem to be crowing yet. I'm really curious if the very first egg a chicken lays can be fertile? It was just such a beautiful and unexpected colored egg. The eggs the pullets hatched out of were pale mint colored and the roo that fathered the pullets is a Wheaton Ameraucana.

Aside from the fertility question, I'm also trying to figure out parentage of the pullet since I'm trying to recover my original type chickens slaughtered by a pit bull. I gave a relative a Wheaton roo, hen, and buff hen, all Ameraucanas. She also had a BCM, a solid white EE with greenish legs, a brahma and some solid light grey hen with a single comb. The BCM and Brahma have feather legs the pullet does not.

The pullet came from that bunch. She looks like your typical EE, mostly red with black markings, muff and beard, but bright yellowish orange legs. So now she is officially a dark olive egger with spots. Who is most likely her mother? I asked my relative to give me her blue eggs and got like I said, late season pale mint eggs.

Of course it can. All it takes is a male capable of fertilizing the egg to mate with the pullet a few days before that first egg is laid. You can check to see if it is fertile by cracking the egg and looking for the bull's eye. This link tells you what to look for. Crack the egg in a small bowl. If the spot is underneath the egg gently turn it with a spoon. Do not break the yolk, be very gentle.

"Can" means it is possible it is fertile. It does not mean that it is. The male may not have deposited his sperm. Even if it is fertile that does not mean it will hatch if you incubate it. I find that I get a better hatch rate and larger healthier chicks if I wait until the pullet has been laying for at least a month before I incubate any of her eggs.

I'm aware, that it's possible for an egg to be fertile, I just wanted to know if anyone successfully hatched a first laid egg. It just doesn't seem likely the first egg could hatch, though I'm giving it a shot.
