Yes. You can let those two pairs out too (although it's best not to, so that you have breeders to make more babies) after about a month. They don't fly a whole lot, but you can let them out for exercise.
That was my first question before I got my dragoons. You can definitely loft fly dragoons. I've taken mine 10 miles out and they make it home just fine from that distance but you have treat them like your homers and fly them every chance you get from the minute they are weened so they are conditioned to fly.
