They will certainly be more than stiff. Be prepared for the wings to flap and legs to kick after the head is off. I don't mean to be grotesque, but you should be made aware that they don't just go stiff suddenly. You need to hold them down else they will flail quite a bit. I butcher quail, and even they can move enough that they will slip out of my grasp. Wrapping a towel around the wings snugly and holding the feet is helpful. Its similar to s come in effect, but softer and possibly comforting for the bird to keep them calm.Cannot do the cone. Watching an animal bleed out is beyond my scope of capability. Might do it to make a quick cut but no artery snipping for this gal. Idk why but to me the cone method seems very impersonal and barbaric and scary for the animal...upside down in a device with someone pulling your head. I considered a cone type something for at the chopping block. My dad never had issues though. Have to be pretty bad to miss a 2 inch neck with an 8 or 10 inch cleaver lol. I saw him hold them but never watch him strike them. They did nothing more than look frozen stiff once held down. But yes I do have more research to do. Thinking my buddy down the road will have to come do these 2 cockerels while I learn. Maybe her method will be something I am capable of.
