The books I see as reccomendations the most are:
give your dog a bone
and
grow your pups with bones
Does anyone here think that they are great books?

Give your dog a bone was a good starter book for me. I learned a lot from the internet too (the rawdogs community on LJ is awesome).

Do you really have to have a chest freezer in order for the BARF diet to be cheaper than kibble?

I only have two shelves for their food and right now, I'm paying roughly the same price as I was paying for kibble. I buy premade raw (mixed veggies and fruits).. I'm sure it would be cheaper if I bought in bulk. It would be even cheaper if I did everything myself (I'm too lazy ).

OR does it matter if I feed a LOT of one type of meat for a while? I can buy one item in bulk at least to store in my freezer.

Your pups should be fine if you choose to do this. My boys get two meals a day and at least one of those meals is always chicken (bones). It's cause chicken's cheap, and it's easiest for me to find chicken bones. I read somewhere that chicken is one of the better meats to feed too.
