Did my tortoise lay eggs???

[beaubeaumont]

This morning I found two smooth white pebble like things in my torts enclosure. I initially thought my boys must've been messing with them, but have now come to what seems like the only possible conclusion - eggs!

So I have a few questions...

Can tortoises lay eggs with no male present?

Is one of my tortoises male?

What do I do with the eggs? (I'm assuming they are not fertile)

I have two UK captive bred Hermans, they were hatched August 2008 so they are 8 years old. They were incubated to be female so always assumed they were both female. Now looking at them I think one may actually be male.

I'm not sure how to upload photos but one of them has a considerably longer tail than the other, that's the only difference really.
