Freezer burn is mostly in people's heads. I've eaten meat that's been freezer burned and it's not so terrible. All it really means is that it's dried out. The same people that pay for jerky throw out freezer burned meat. Why? I'd eat those doves for sure!
If you keep your deep freezer at or below 0 degrees, it should be good indefinitely. Assuming you keep a decent, odor free freezer. I have eaten meat that was in the freezer for multiple years and it still tasted great.
