The secret is practice, practice, practice.
It takes 7-8 weeks of practice before a young crane colt can fly. From the very start, little Arrow waved her wings as she walked about. By 5 weeks of age, colts are running 10-15 yards as they flap their wings and jump, trying to catch air.
Roy and Millie are coaches - prompting, encouraging, and rewarding the colt's efforts, with food, with purrs, and with dances.
Both Arrow '15 and Pi '13 are featured in the video below.
