Does anyone have a number for me on what a 3 week old Cornish Cross ought to weigh? I know I have slowed mine down by the way I am raising them (free range, lots of excercise and not on broiler food), but I'm curious how far behind they actually are. Also, have any of yours been able to fly at that age? Mine are surprisingly good at flying, running (they're hard to catch!), and also roosting. They can fly up about 5 feet and perch on my shoulders!
