These are 10 month old Arizona Desert Tortoises. I took this video 2 weeks ago. I saw the bigger one bulldoze under the little one tipping her over on her back. Then I grabbed my camera and observed the rest. Since then I have changed a lot of things in the way they are housed and I have not noticed anymore of this kind of thing between them. So I'm really just putting this video up to see what you think....bullying or just an accident due to being in a small space?
