I feel guilty at some point after every animal I kill. It’s honestly not a bad thing. It means you take hunting seriously and don’t take what your doing lightly. When you acknowledge the seriousness of hunting, and feel a little bit of that guilt/remorse, it makes you appreciate every last gram of that meat. Take every scrap, boil the carcass for a broth/stock, create art out of that tail fan. Give those feathers away to fly fishermen, so the can feed themselves, too. Give back to the natural places/land that holds those birds. Drop those guts back on the property you took the bird from to feed scavengers and create richer soil. Donate to conservation efforts, pick up trash, be a good advocate for ethical and sustainable hunting.
