ok, I may have been sold the wrong breed! I was buying cornish X from a local store.. and bought 2-of these birds. They were yellow when I bought them! Do we have a mix-up? One interesting note; I have 5-week olds heavy layers, and this guy pictured is just 3 weeks old. The 5-weeks are at 10oz, and these guys are too! What is your best guess as to the breed of this 3-week old bird?
