Yes.
I rest cleaned carcass in the fridge for 2-4 days before cooking or freezing.
Well that explains a lot. The lady that did my butchering assured me those 4 and 5 year old roos could go straight in the freezer and they were tough and stringy. I rested my young ones, mostly by accident because I planned to cook them and just didn't get to them right away, and they were delicious! Lesson learned. Thanks!
