Limiting pellets?

The general consensus among chin keepers seems to be that we should not limit their access to their staple foods (hay and pellets). Apparently most chins will not overeat and they should be given the opportunity to eat however much they want/need. But what if your chin is a pellet fiend?

Margaret LOVES her Oxbow pellets. In fact, she loves them so much that she will eat an entire bowl full within an hour or two. I recently measured how much her bowl held, and it will hold about 2 1/2...
