Never tried, but I think it would work. Oxygen is the enemy, but the reason is because oxidation leads to other byproducts that lead to a stale flavor. I believe the cold temperature slows all that down.

I only interned there, but the handful of times I thawed the chips, there were no issues.

You can freeze chips/crisps indefinitely. I used to work for Frito Lay. Just thaw them when you get close to snack time. Of course I never do this because I just eat the chips I have at home.

The bird makes a call that sounds like the word “dee”, over and over. Just as someone who runs is a runner, a bird that’s dees, is a dee-r, so it’s not deer in the sense of the animal the way you may think. At least that’s what I’ve been told. The “kill” part is a bit strange, but I’m assuming it comes from the fact that this bird will feign a broken wing to distract a predator away from their nest. All in all, I’m really not sure on the origin of the name, but that’s what I’ve learned in my last 3 years of actively being a part of the birding community.
