I have to agree, fantails...either American or Indian shouldn't be left out to free fly or wander around because they will be picked off by predators very quickly. I used to raise them along with Jacobins and Capuchines and I did let them free fly several days a week for excercise and always watched over them like an old mother hen, but no matter how well you think you can watch over them...you can't stop the strike of a hawk who seems to be drawn to them like a shark to blood. So I just had to build large aviaries where they coudl excercise and be protected at the same time. When you start showing and dealing with breeds such as these that can cost a lot whenever you get into really high quality stock, you don't want anything to happen to them and just can't take the risk. There are some other breeds that aren't well met for free flying either.
I believe that is why a lot of folks started breeding the Garden Fantails. They make a better aviary type and free flying bird because eventhough they have the fantail, they are upright like an indian fantail, but not as bulky. They are meant to fly and fan at the same time. They have been breeding them for quite a while and are usually the result of crossing between homers and fantails. You get an upright bird with a fantail that can still fly well and see to get around, but they are still not immune to attack.
As stated above by other fanciers, American Fantails just aren't built to be out much if at all and soon will become prey to almost anything that has a notion to eat them.
