I have a female and male Russian tortoise that have mated within the past month. My female started to show signs this week of nesting. Being restless and digging test nests. Two days ago I found her digging in their outdoor enclosure. This time it was an actual nest, digging with her back legs and the correct shape for the nest. She covered it up and a few hours later I carefully started to excavate it for eggs but found none. Two days have gone by and she has stopped digging around. Can someone give insight on what's up? Very concerned if I should take her to see the vet.
