I remember learning this skill as a young second class. We had some lectures from a very qualified ASM. We started with watching him field dress a deer. He explained how that process was similiar to a steer, and where the hamburger was made. We learned how to use every part of the deer with nothing wasted. It was amazing, probably one of the most memorable experiences I have. We were then shown a 'survival kit' and directed to make our own.
The best part was the overnight experience. We 'planned' an outing, including food, water, and shelter. The adult leaders, without our knowledge, had a better learning experience planned. We packed all of our gear on friday into one of the leaders trucks, and basically went about our business. We showed up, like always at the jump off point for our trip, assumed all of our gear was in the truck, and took the hour ride out to knowwhere. The adults had done a great job of 'planning' and when we arrived at the rustic site, we went looking for a good campsite. Boy were we amazed when we went back to find that the truck had left, leaving none of our gear, excecpt the kits that we had made. The SM and ASM were sitting on the ground by a tree, waiting for our return. We were completely shocked, and the surprise added reality to the event. The ASM had a burlap sack that he said was full of our dinner. The SM laid out the rules for the event. We were stranded/lost and we needed to work as a team to survive the night. The burlap bag was so distracting, what was in it, you might ask? We had no idea. Shelter was priority one. DONE. Water was priority two. DONE. That burlap bag was finally opened about 2 p.m. The look on our faces was probably a VISA moment, especially when the ASM released 6 live chickens, with a raucous laugh, followed with, "Dinner is served!" We spent several hours just trying to catch the chickens. I cannot tell you the fun/fear we had. It was AWESOME. The whole time we were being observed and taught what to do. I am pretty sure that we scared every 'real' animal away from our area with our running, laughing and screaming, so snaring a wild rabbit or squirrel would have been impossible. Once caught, we had to kill, clean, and cook the birds. I will apologize for not following the LNT principles, because who knew how many feathers were on a chicken. Some guys didn't remove the feathers and cooked them off, Some got most off, while my group peeled the chicken. We ate every piece of edible meat off that chicken, and it was terrible. It was completely overcooked and had no flaveor, but it would have kept us alive.
AWESOME EXPERIENCE. Good on your PLC for wanting to add this to their plan. Please don't drop into a pet store and ask for a rabbit for stew, though. 'Domestic' animals are not for eating. The yellow pages is your best choice for looking to find 'wild' animals for food.
BTW, this happened in 1982.
