I'm still working out the best system for me. I was putting each portion into a small ziplock bag, then each meat type/cut together into a larger, labeled ziplock bag. The bags don't take up a lot of room in the freezer (bonus!), but the masking tape labels didn't stick, the larger bags are hard to reseal after a while, and the bags leak blood all over the fridge while thawing (that's what I get for using cheap bags, I guess). Additionally, since the bags were leaking, I stopped saving them for re-use, meaning I am throwing away a LOT of plastic.
Also, I'm not great at remembering what I gave Kip to eat yesterday, the day before, etc., making it a bit harder to keep track of bone amounts, organball numbers, etc.
So, on to Plan B. I bought some cheaper plastic containers, large enough to hold 4-5 days worth of food. I got 2 to start with, as I don't want to waste a lot of money on a system that won't work any better then the one I'm currently using, but it gives me something to start with. Below is one container with 4 days worth of food - a large turkey drumstick, some bone-in chicken and boneless beef, along with some organballs.
