Nice job!Success! The rest of the boys are done, and they went peacefully, with no squawking.
I ended up borrowing a friend's knife sharpener, and we undid the damage that the professional knife sharpeners did, and got it cutting paper easily. So between that and giving the cockerels more time to calm down once they were upside down, they didn't react at all when I cut them. I'm really pleased with how these last guys went. We are done with processing for now, but I'm sure I'll hatch more cockerels and need to do this again eventually. So I feel much more confident with my ability to do this quickly and humanely. Yay!
