Air sac

[BrownFamFlock]

I have 2 Sebastopol goose eggs incubating under a broody chicken. I purchased these on eBay and let them settle narrow end down for 24 hours prior to putting them under my hen. Both eggs show signs of movement/life. My question/concern is that one egg has an air sac considerably larger than the other egg and the air sac looks irregular in shape. Will this affect hatching?

Do you have a picture? It might be a saddle air cell. It should be fine. I've hatched several with saddled cells and both of them made it.
