I am raising some Dark Cornish this year for meat and plan on butchering them at between 17 and 20 weeks. I also have some roos from the straight runs I got for laying stock. I have 2 Cuckoo Marans, 1 RIR (a surprise roo), and 1 Buff Cochin (the free exotic chick). One of the Marans is crowing so I have to do something. They're between 12 and 13 weeks right now. I've tried Craigslist but no go yet. Are they worth butchering at this age? Would there be any meat on them? I wouldn't gut them but just skin them and take off the breasts, legs and thighs. I don't know if I can do the Cochin. He just doesn't seem like a meat bird. Any advice is welcome!
