So I decided after weighing all the pro's and cons (or improbablility) of trying to hatch a double yolker I would give it a try. Yes I knew what all I was taking on. My question is , there seems to be only one chick developing in the egg. Would this be a possibility? The egg is HUGE and there were definately two yolks to begin with. The air cell has been developing on the side though. I guess I will just continue to monitor the one baby I can see move for now and hope there is another one under it or something.
