Approx 13 yr old Herman's and she is suddenly doing lots of digging with her back legs, googled it and thinks she want s to lay eggs. This has been going on for a week or 2. Can't get hold of any more substrate until a week ahead to give her more to dig into and lay eggs. Is it ok to let her loose on the soil border in garden (obviously will keep a watch on her at all times). We've only ever let her on the grass, border seems to be clean, as in no cat poo or anything.
Advice greatly appreciated. Thanks
