gestation period

[hollycham]

Hi guys, I'm pretty sure I m close to the correct answer but thought I would ask all the experts on here.
My male and female breed about a week ago....my question is how long will she stay gravid with eggs before laying them? Im pretty sure it is just about 30-40 days am I correct?
Any information or comments would be appreciated
