Muscovy egg with air sack on side?

[sevenchickens]

I just candled my 14 Muscovy eggs and found 13 little ducklings dancing around!!

One of the dancers has an air sack nearly (not entirely) on the side of the egg. Is this going to pose a problem for hatching?

If it is developing I'd say it should be fine. I have had entire hatches of shipped eggs like that and decent hatch rates.

This was a shipped egg too. I was very pleased to have the rate of developing eggs I have.
