Aggressive Ball Python - HELP!!

I guess it depends on the snake and the actual size of the feeders.

My 500 gram females take one adult mouse and one weaned rat every week, which with my feeders is about 15%.

The time line however, I think is about right. Start with one weaned mouse a week, then when she is big enough to take two weaned mice in 3 or 4 weeks, try an adult mouse or rat pup. Feeding one rat pup each week, in another 3 to 4 weeks, she should be big enough for a weaned rat.

All of my snakes had roughly this same feeding schedule but one problem feeder, and all grow at a consistent rate and are not fat.

Of course, if his cannot take two weaned mice in a months time, he should wait until she can take two in a feeding before moving up a prey size.
