I have a BO roo whose legs do the opposite--turn inwards! I'd love to hear what people think might be causing this! Is it a birth defect??? He didn't seem like he had this problem till a few weeks ago!
when dealing with a chick with slipped tendons i did learn from the poultry orthopedist that their leg bones can grow twisted. i think if you catch it early you can splint. here is a link to his board http://www.voy.com/194762/ maybe he can help.
