There will be a lot of ways to do it, but I agree with the others that you just cut one slit and tear the whole skin and feathers away with your hands. I know a guy who plucks and scalds his turkeys and leaves the skin on for cooking, but it seems like a waste of time to me. Just take out the breast meat and the legs and thighs and you are done, if thats legal.
Depending on where you are hunting, the laws are different. Here in Missouri, throwing away any commonly edible portions of your game animals will get you a big fine, so just taking the breast meat only, for example, is illegal, and can get you busted. Check your laws where you hunt. Plus it may be up to the interpretation of the officer what portions are commonly edible, so I don't take chances. I'ts common for instance for a store bought turkey to be whole, with the back, breast,wings, legs and thighs, and the neck, heart, liver, and gizzard stuffed inside, and they are of coarse edible. You run into an officer who's favorite part is the heart and liver and you've thrown those away, and it could be a fine. It's unfortunate that so many hunters don't read or understand the laws before they hunt, and get in trouble. We had a new game warden in the area last year who ticketed people for not signing their hunting permits before hunting. He'd ask for the tag, they'd hand it over thinking they were ok, but they'd forgotten to pay enough attention to read the NOT VALID UNTIL SIGNED part, and thats $150. fine for hunting without a valid permit. Now locals who buy tags regularly, have no excuse anyway, and non-residents should know the laws as well before they hunt here. So just know your laws before you take anyones advice and cause yourself trouble.
If your state has laws about wasting meat like mine does, and you get caught on your way home with only a breast, and maybe you haven't taken the time to make the phone call to check it in or something it can be trouble, even if you have hours left to check it in. I saw a guy pay a fine last year for leaving the front shoulders in a deer hide he was throwing out, and another pay a fine for removing the backstraps (because they are his favorite part and he wanted them on ice immediately) before calling the telecheck number and officially checking the deer. Game warden arrives at truck stop, sees deer with backstraps removed, reads the number off the trans. tag and finds it's not checked in,and fines the guy when he returns from his lunch, because he had begun processing the deer before checking it in, as the law requires. These computers now days can trip you up, because the game warden will know the exact minute you checked in your bird, and if you already skinned it and put it in a cooler so you could go to lunch, you're screwed, even if you have 10 hours left for legal checking. You can't miss a step anymore.
