My advice when breeding any snake that eats other snakes is to feed it well shortly befor atempting breeding. With my female kings I give them a big meal (as many mice as they want) so that there is no way they should be the least hungry befor breeding. I also do the same with male kings thow they are less likely to canabalize. Most males will choose a mating over a meal.
