Do you agree Captive Breeding for Swiflets?

My view from the point of research and observations.

Swiflets need a lot of body movement,that explain why birds fly out early in the morning and return at 8 pm. The high antioxidant level in their blood comfortably allow them to do so.
Captive Breeding is the reverse. Birds flying within a constraint space, which restraint oxygen intake for metablism. Birds were fatter.

Swiflets feed on more than 26 type of insects.
Captive Breeding only feed on prepared insects which is not substantial for health.

Swiflets flying high up above sea level( about 2000m to 4000m ). The ozone level do help in sterilizing the body.
Captive Breeding only allows small space of movement without sterilization space.

Swiflets only flying within their own colony without mixing with other birds.
Captive Breeding has close contact with human. The transmit of disease is possible from human to birds.

No Successful Captive Breeding cases till now even the projects started 7 or more years ago.

Conclusion: Captive Breeding for Swiflets is not advisable.
