i definitely wouldn't use that kit. You need some kind of spreaderlll
I wouldn't use that instrument set. You want a ratcheting spreader for the ribs, a blunt hemostat, and a spoon instrument with a notch cut in the top...and cyano acrylate unless you want to suture. i just glue them and take...

I have caponized a lot of birds and did side by side blind taste tests...and it seems kind of pointless today with the meat birds. I caponized a bunch of Bresse cockerels and the "run of the mill" meat birds tasted way better...even after feeding the Bresse cracked corn in whole milk for three...
