Need some advice on my female digging in her lay bin it’s been 7 days now and she is still going down and digging every day she has not been mated so they will be infertile but is 7 straight days too long we covered her Viv when she first started digging and are both at work full time during the day and monitor her through a camera in the Viv but are now staring to get concerned about how long she has been digging for is this normal or should I now be looking at getting her to a vet
