I sometimes will take another male that is the same size, or better yet slightly smaller, and that I have cycled cold as well and I will place the two males together. I will monitor them, but they should begin to battle, usually in very short order, after being placed together. I done this several times, both to observe this Royal Python mating behavior, and to get my shy male worked up and ready to go. In nature, the males will battle over females and this is a way for nature to (in most cases) select the largest, strongest alpha male to procreate and pass the best genes along to the next generation. During the "combat" encounter, the males will sort of entwine their necks, with each male attempting to gain the upper hand and force the other's head down into the ground and make the other submit and leave the breeding to the more dominant male. They will get pretty active and push each other around, knocking over water bowls and bumping up against the sides of the enclosure. While I have read stories of males biting each other, I have never observed this behavior in Royal Pythons? It is really facinating to watch and it definately entices the males to want to breed the females more aggressively. The one thing you want to make sure of is that you NEVER leave the males unattended while combating, and always seperate them when the have had enough.
Good luck!
