I have 2 serama eggs that are twins! Not sure what to expect but I'm going to go through with the incubation process.

Double Yolkers don't mean twins. Double yolkers are often laid by younger hens. I once bought some eggs at the supermarket and Every single egg in the pack, LIKE EVERONE was a double yolker.
