I know this question has been asked before, but I was thinking about raising a cornish cross as a pet/laying hen. I know they get big really fast but I was wondering if I raised it on regular chick starter and eventually regular laying hen food, would it turn out just fine? I would definitely keep an eye on her weight but does this sound like an ok idea. Do you think she would live as long as regular hens like over 10+ years, possibly 20? Would she get along with my regular laying hens?
