I recently adopted a 7 year old red foot about 3-4 weeks ago. And just this pass Sunday, I found another red footed tortoise in the middle of a busy road. Since these guys are basically large sized, I have them roaming my backyard which is about 3000 sqft. Yesterday was the first time they actually noticed each other. The first tortoise I brought home immediately started making sounds and eventually mounted the newer tortoise. I believe they are both males because their bottom shell is caved in. Am I correct on this? They seem to be fine with each other. Can 2 males live in the same area? Should I be more careful with their encounters? Is the mounting showing dominance?
