I have a Hermann’s Tortoise that I let roam in my backyard when I am outside. Last Wednesday I got distracted by my young son and forgot my tortoise was out there. When I went back out 2 hours later I couldn’t find him. We have a small backyard that is fenced with no grass but lots of plants and bark chips everywhere else. I am wondering how deep they dig. If it is possible that he has found somewhere to dig and has been hanging out there for days or if it is more likely that he managed to climb under the fence (would be difficult but maybe not impossible). I have alerted neighbors but nobody has seen him yet. I am pretty new to tortoises and am not clear on their outside behavior. When I was with him he would usually roam around but I did catch him digging sometimes. Just not sure how deep he would dig and if he would stay there for days or what. It is about 50F where I am at night and mid-70s during day where I am right now. Any tips on finding him?
