Text for Video Clip:

Pilot Joe Duff: Now when we start, we have an old group, a young group and a middle group. We mix the middle group with the young group and then we introduce the older group. That way, if we mix the old group and the middle group, then the young group would be left out and when it came time to mix them, they'd be outnumbered. They're the smallest birds, and the other ones would all be established and we'd have to introduce this new cohort. So we mix the young group and the middle group first, and then later on bring the old group.
