Like Snakes mentioned it could take months. I breed my females from Nov-April last year and they laid clutches from June-August. Keep the pairings going the more locks the better as it is still early.

You may also want to look for videos on youtube on How to palpate so you can check for follicle development throughout the season. There are some good videos out there.

Unfortunately, I have not mastered it yet so I would be no help.
