well if you use like, 7 shot or something a 12 guage is fine, but you wanna have some useable meat left

. If you have a .22, that's perfect. As far as field dressing it, most of the meat is by the legs, and they taste great. Boil em first, then throw em in a pan with a cover with somesome grapseed oil, or even a little ginger ale, then throw em in a stew. You get 2 that's a good meal for one. Good luck, it's alot of fun.
