If it's not your "thing" then don't do it. The meat is fine to eat without but it is my understanding and personal experience that letting the bird rest in the frig a few days makes the meat less tough. Biologically it allows the lactic acid in the muscles a chance to dissipate. The resting period makes a bigger difference in larger game but I have found it also makes a difference in my older hens. The first time I processed I did not rest and the meat was extremely tough.
