I feed my adult male BP a medium rat (anywhere from 165g to a bit 0ver 200g) every 10 days or so. For my adult male that bred this year, I'm feeding him every 7 days as long as he's eating so that he'll put weight on. He fasted for a couple of months when he was with the female.

How much does your snake weigh? I've found it's much easier to deal with them by weight than age/size. The same with feeders. If you can pick up a digital scale it helps a lot. I found one for $30 at one of the local stores and it works great for everything up to my adult BPs.
