Omg. Eggs!

I've not seen any veins, how long should I wait before I know for sure they aren't viable eggs?

With ball python eggs they either have good veins structure when they a laid or they don't, if it's not there it's not there, now in other species what can appear from weak to almost non existent can develop to a good vein structure in a few days.

Never had ball python eggs, so I'll take Deborah's word for it.
