I have a 50 lb. male sulcata. I am fostering another male of the same size; he was found locally and we have been trying to locate his owner but with no luck so far. I would like to keep him but only if it doesn't create any chaos or extra work (such as separate quarters). My tort has a pen but free ranges most days on a fenced acre and a half. We had a brief introduction which consisted of a face to face meeting (literally), progressed to a little nibbling, and then looked like it was possibly going to escalate into some pushing, at which point we separated them. So, I have searched the forums and see that it seems to be a case by case basis as to whether they will cohabit or not. I'm interested in any personal experience, such as, how long to give them to see if they will work it out amicably, or any other advice. I have people who are interested in giving him a good home, so would rather do that sooner than later if that's going to be best.
