I'm very interested in breeding my own Cornish Cross someday! I know the famous mix was a Cornish rooster over a White Plymouth Rock hen. Wikipedia told me that that wasn't what today's cross is (at least that's what I took from it) What is the best mix to get fast growing, meaty birds? Obviously they won't be exactly like the ones you buy as chicks, but as long as there is lots of meat, I'm okay with that! Thanks in advance!
