What's up with my female??

[silverbill]

When was her last shed. It sounds like she may be ready to lay. Does she look ridge backed? Have you caught her lying inverted at all or twisted like a pretzel? All of these are good signs of things to come. I hope she goes for you.

She last shed in May this year. Yes, she's looking very lumpy and ridge backed. She often lies on her side in a coil. She shows all the signs of laying soon but it's been 3 years and nothing. I've only ever paired one male with her and he's not proven. Could it be the male is dud and triggering her to go into "false pregnancy"? I'll probably try with a new male this fall if she still doesn't lay.
