How much do I feed?

[DennisM]

Rule of thumb is 10-15% of their body weight.

an even better rule of thumb, I think, feed her something about the same girth she is at her thickest. a far less known rule of thumb (because it's my personal experience, not a community consensus); if it takes the snake more than 15 minutes to ingest the meal once started, the meal is probably larger than necessary. if it takes the snake less than 5 minutes to ingest once started, the meal is too small.
