I have had to cull a couple ducks, and the hands on for a grandma who is squeamish...and the ax method for one person is awkward and took more than one strike. I was looking for a way to stun first and not have squawk or fear; just so sudden that they are knocked out. I searched forum for shooting first as it is less hands on (it is still hard to cut head off, but if it is dead or knocked out , it's not the same.... so reading and searching pros and cons... I wanted to start small first. We got a pump pellet gun, that you can pump up 10 or so times .....Duck had been injured somehow in pasture and seemed unable to stand or walk, I isolated and checked it and fed it 24/7 and after a couple weeks it still couldn't walk or stand...decided it may have a spine injury (it was in a pasture with African geese who usually leave them alone) or maybe another drake etc. So I finally did the deed. I had a stick handy and ax in case it failed.... I restrained him in a feed bag with hole cut out and he was calm and sitting. I did miss the first shot, (not close enough), I then put it point blank on the back of his skull, and fired once. (over 10 pumps .22 pellet)I could tell by the change in it's eyes, like a light went out, no squawk or convulsion, just limp, and blood then came pouring out of the hole. I quickly pulled out of bag and 'tried ' to use my heavy duty 2 -3 1/2" loppers, maybe t it was the angle, but 3 attempts didn't cut it all off, so I then resorted to my ax...2 strikes... (even after sharping...it is old).... It may have actually killed the duck, but at least it was stunned and was much less heart rending than the just chop while conscious . I have a couple others I have to dispatch too and think I will use this method, it is quiet, cheap, and not likely to hurt anything else.
