Helllp (shouted like scooby doo!)
 

My female has laid a egg lol, (we do have a male) I could only first one so my first question is are there more ive not found or is one normal for a 1st lay, Ive got it on some moist vermiculite in a incubator at 29c, I'm getting so much conflicting advice not sure I'm on the right track.
thanks for any advice offered.

Hi which species please? Be careful dampening the vermiculite (if med species) as eggs can crack if too damp. I find it better to sit the eggs in dry vermiculite then add a wide mouthed container of water to pprovide humidity. :)

As has already been said species and size of female may give a clue on clutch size. Often females may drop single eggs if no suitable nest site is available just to ease their discomfort.
