I have a small hatchet, and a knife on hand, and 2 small boxes, one for meat the other for skin, with feathers attached, and left overs. When I butcher the roosters are about 12 weeks old. It seems easier to skin when younger. I drape the body over one side of a stump. Neck on top. They will struggle then go limp. When limp I chop neck, put head in box. I let the rooster jump about 5 min.till still. Then chop legs and wings off. I poke my knife into skin, then I rip the skin off, it comes off easy when fresh. Comes off like a coat. Feather skin goes in toss box. I bend hips way from body, cut off legs. Then I cut the shoulder blades from the back, then cut the breast from rib cage. Being careful not to cut into guts. It takes practice. I peal breast bone from back bone lifting up. I remove heart, and liver for my dog.Then in the end, the guts and backbone still connected goes in the toss box.
It takes a while to get it right. I cut my finger really bad and had to get stitches my first try.
