You're probably right. But either way, there is rigor mortis that must be allowed for whatever way you do it. I've been told by a former mortician that now raises chickens that they can go through rigor mortis in the freezer, it just takes a lot longer. Or be set in the fridge for a few days first. Either way, it's gonna be there.
I never said it (rigor) wouldn't be there, I wanted to explain that instantaneous rigor is different from rigor. Everything that dies is going to experience some type of rigor, but dealing with instantaneous rigor is a problem that you can avoid if done properly. As for going through rigor in the freezer, I can't answer that because I always let it set in the fridge a few days first. I learned from processing and dispatching rabbits that the meat is best to let rest in the fridge before heading to the freezer.
