One tip for using a chest freezer--not just for meat, but any chest freezer:
Buy some plastic baskets to organize it before it gets full (milk crates are great to use if it's a big freezer, or find appropriate smaller, stackable baskets for small freezers). Group things by type in the baskets. If you organize this way, when you inevitably want to get to the stuff at the bottom, you just lift out the top basket, and it's easy to get to the stuff below. The milk crates can even be rotated top to bottom from time to time. It also makes it less likely you'll forget ("lose") good stuff at the bottom.
You can find assorted plastic baskets at Walmart in several different departments: sewing notions, bath items, organizing, and laundry -- write down your inside freezer dimensions to take with you to the store, so that you can put some together that exactly fit your freezer.
I also recommend hanging a white board next to the freezer. I have the board divided in quadrants corresponding to my baskets, and I list the contents of each basket (and the date the item went into the freezer). When I want something, I know right where it is going to be found, so there's minimal digging.
