Ok... so today is day 7... and the egg is infertile. But, I will keep looking for double yolk eggs, I have 5 young eight month old muscovy hens, so I am sure I will get plenty. ( I had one of them lay 2 double yolkers in 2 weeks! )
If I find some more and decide to incubate I will post on this thread.

What ever happened with your double yoke? I have one in the incubator now and I noticed the air sack doing the same thing you described.

It was infertile and never hatched.
