I wasn't very sorry. Scratch that, I wasn't sorry at ALL. It killed two out of three of my ducks, which I loved dearly, and the third later died of complications from the attack. Those birds were my obsession.
They're quick little buggers. I sat by that pallet for quite a long time before I had the idea to use ether to slow it down so it couldn't pull back under every time I took a stab. I hope you get it, those beasts are completely devastating. :hugs
I killed mine by trapping it under an iced-over pallet, squirting ether under there to slow it down, then cutting its head off with a shovel. Kind of hard to replicate, though.
