Well you need to get the male to around 800 grams, dont power feed him its not healthy for the snake. I feed my males 1 regular mouse a week till they hit about 300 grams then offer him 2 a week if he wants the other mouse. takes about a year, and your still not gaurenteed the male will breed yet. Some males breed at younger ages but thats not the norm. So all in all i breed mine at about a year to year and a half and if they are in good health. Good luck hope that helps.
