Hi, I've just built my tortoise and outdoor run. He is a 5 year old Marginated tortoise. My problem I am having though he doesn't seem to like it outside. I've been putting him outside for the last week and everyday all he does is dig and hide in the same spot all day. He's not even interested in eating outside. The second I bring him indoors at the end of the day and give him the same food I had outside straight away. He just doesn't seem comfortable outside. Any help in making him feel more at home?
