So I was thinking about this tonight.....in the past I have let the chickens sit in a cooler or fridge for a few days and then vacuumed sealed and froze. I know that some people seal them and then let them sit for a couple days. Is there a correct way to do this? My thinking is that sealing before letting them sit would not let the oxygen get to them and assist in the rigor passing. What is everyones take on this?
