How common are they? We apparently have a chicken that is prone to laying them. I think we've had 4 or 5 so far and they've only been laying about 3 weeks.
My brother studied poultry science and is in vet school at Auburn and we just had this talk this past weekend after finding one in an "extra large" egg carton. Apparently its roughly 1 in every 1000 or .1%. Its caused by a hormone change/imbalance so some chickens are more prone to lay them than others. He says its typically found in new layers and older chickens. Pretty interesting

These are new layers and the other eggs are tiny, these appear to be more normal in size. Hoping the others increase in size and the double yokes keep coming.

By "extra large", I meant the size on the carton bought at HEB. I'm guessing hormones given to the birds cause it. Though, the double-yolked eggs will be slightly larger as well. Judging by the other responses, I'd say the double-yolks quit as the chickens mature a bit.
