Freezer burn is ice sublimating to the gaseous stage. As far as I know, this takes only water out of the prey item and wouldn't affect nutritional content at all. In fact, you could probably argue that freezer burned prey are easier for your snake to digest because they have suffered some degradation already. Someone correct me if I'm wrong here.
