Double yolker question

[pbjmaker]

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.

The other one could have died early on. BUT the other one can still survive with its neighbor being dead.
