To save on time, I take one day out every now and then and go buy everything and then package it up to make things easier. If I buy chicken quarters, I seperate them all into little baggies and then freeze them until I am ready to feed it. Otherwise a lot of things freeze into clumps and you have to thaw the whole thing to get the portion you want out, which is a pain.

My mom buys Wal-Mart deli bags on E-bay for about $.01 per bag. I package everything up into a meal portion and then freeze it all. You should see my freezer, it's so organized

It takes a couple hours if I do it myself, but only about 30 minutes if I have help. My mom holds the bags open and seals them while I drop stuff in and cut up organs into portion sizes. Then when I am ready to feed I just put the dogs outside and go get four baggies of something from the fridge or freezer.
