"spiderweb" marks on eggs?

[ReneeB]

I remember seeing a pic of the same marks on some eggs.. [joe and melissa????]

The spots look like little spider webs. is this a calcium problem? I remember reading something similar..

And can you give extra calcium by dipping prey items like with Leopard Geckos [dusting crickets with calcium powder]??

[Joe]

First I would like to say that all the eggs that had the calcium deposits, everyone of them hatched I dont think it's a problem at all...but yes, you can dust prey items with calcium, some of the smaller colubrids would benifit from this, like mountain kings and such
good luck
