Yea that’s a great question! I didn’t even think to ask that.Just wondering if you only have two colors of eggs, because each hen lays a specific color. I can always tell which egg came from which chicken and I have a nine of them.I would say that if you have more than two different tints of eggs then somebody is pulling a prank. Have any of your friends or family ever owned chickens? Usually people that have never own chickens do not know about the whole brooding process. It could be some weird kind of miracle on the other hand.
