Braxton Hicks! Never thought about that but... Now I want to know!!I'm no expert on breeds, especially with but a photo to go on, but my best guess would be a black australorp. They should lay light brown eggs. My thinking is that she may not be the hen that laid the egg, even though she sat as if she were trying to do so. Do chickens get Braxton's hicks? Haha. An Ameraucana doesn't usually have those wattles. I suppose there are always exceptions, but that photo doesn't look representative of an Ameraucana to me.
