Feed question

I have recently begun breeding mice to feed a single (for now) ball python. Our local feed store carries Mazuri 6F. In researching I see there are three Mazuri products for mice breeding 6F,9F and 11F. Am I losing anything by using the 6F instead of one of the other two products?

For what you are doing you won't see any real benefits to feeding 9F or 11F. Those are only for "high output" breeding

A good analogy for them is mid-grade and premium gas. You only use them if you have an engine in your car that requires them or you have cash to waste.
