Fred: If you look you can see that each is feeding off a lure. Since both have more food than they can eat, they don't fight over the food.

Whether or not they will be flown together is still up in the air?

Jeff: At 15 days old, you are not dealing with a true imprint. I would suspect that you will be dealing with fear issues as opposed to aggression issues that you might encounter in a younger taken bird. I've taken a few gosses at day 15 and they were a far different bird than those taken much younger like the 3 birds in this thread.
