One of my female laid yesterday as well and it was just 3 weeks ago since the last clutch she laid ... :shock: !
Around a month is usual ... (for many geckos I think, 2 other species I breed as well the same time period in between!)
I guess it depends of temps & food how quick it goes til next ...
It's quite hard to influence that if you think it's too stressy, because of the depotfertilization (don't know teh scientific term) ...
If you think it's too stressy take the male out if you haven't done it already ...
After a few time it will stopp ...
