Well I'd let them go because to even have the thought, you're obviously not starving or possibly even 'slightly' strapped for food.
I've found myself releasing many more trapped animals since the change in smoking.
I release all waterfowl from loop snares the same. As waterfowl are/were able to pass messages to/from the dead. Tuonenvirta, Tuoni’s River, where dead souls would travel. Waterfowl reaching down with their necks.
Those same mallards, tufted ducks would be found dead floating in the bay, when going fishing. That’s because “once trapped, the creature will die”... which was to stop folks from skill grinding dodge and blocking on trapped elk. Now we can’t release animals back into the wild. Even uninjured ones like any caught in loop snare will die shortly after.
Shame really.
(Btw, British spelling is ... unfortunate ...)
