I commonly use one male to fire up another male. I do not allow them to actually engage in combat. Simply seeing another male is usually sufficient. If that does not work, I will put the 2 males together briefly. It only takes a minute or so, for them to begin firing up. Once they both beard, and begin turning sideways at each other, I pull one male. There are draw backs to this though. One male may submit to the other one immediately, especially if there is a difference in size. I use a mirror if I do not have a male that is comparable in size. By all means, do not let them go unsupervised, even for a moment. You are right, this is a controversial subject, but I have had no problems. Once the male has bred, and been proven, introducing another male is usually not needed anymore. By simply putting the male where he can not see any other dragons for atleast a week, then allowing him to see a female for an entire day without being able to get to her, he will be ready to breed once introduced together. If this does not work, try the mirror technique. If that fails, go ahead and put another male in with him. Like I said, do not allow them to actually get to each other. If they do engage in combat, or one male pins the other, the "loser" will not breed and may not for a while. I had a male that was pinned by another male last year, and he never bred the entire season. Anyways, best of luck. Email me and I will send pics of one male firing up another male.
