I have 8 roos that have been on ice in a cooler since they were butchered Friday (approx. 72 hours). I've drained the ice water and blood from the bottom of the cooler twice and replaced the ice, and they're staying very cold. Should I put them in zip bags and put them directly into the freezer? Should I soak in saltwater in the fridge before long-term freezing? Anything else I should know before storing and/or cooking them? Thanks so much.
