I've just been reading Dr Del's post on his snake and retained eggs which he thankfully managed to get out and rather than hijack his thread I was wondering at what age snakes start to lay eggs? My BP and boa have only just turned their first year, but my hoggy is an adult whose age I don't know, and she hasn't laid any.

So what I'm basically wondering is - at what age do they start laying? do they lay every year? And if there aren't any should I be worried and be taking a snake to the vet at some point to determine if there are any stuck eggs inside?

Just want to be safe
