I'm sorry. I really don't think you did get the CX. I did 4 last Saturday at 8wks on the nose and the two smallest dressed out at 6.5lbs. They grow exponentially the last 3wks and can barely walk now and aren't even 9wks old. Did you get these from a local feed store or order them online? You might want to let the remaining grow out a couple more months if you can for a heavier bird. At 12wks my last cockerel dressed out at 10.5lb and the smallest pullet was 7lbs.
