I have a troublesome 8 week old Wyandotte cockerel. He was bullied a bit by the hens and now he is getting mean. It’s time for him to serve his purpose. But, what is the earliest week to butcher where I would get any amount of usable meat? Like I’m thinking a little Cornish hen sized amount of meat even. I don’t want to waste his sacrifice for too little meat. How long do I have to wait?
