This morning my 3 year old Redfoot Tortoise Murphy did something he's never done before. I cut open a mango a little and placed it in his enclosure, which I do often. He immediately went over to it, stuck his head in his shell and started violently ramming it around his enclosure. This went on for about 5 minutes until I removed it. My question is Does this mean he's probably not going to be able to live harmoniously in a group? Or is this just a puberty thing?
