Interesting article. It's also interesting they referenced the Atwatters prairie chicken. To my knowledge, the Atwatters are unable to put forth viable broods on their own, and the only reason they haven't blinked out is because of the captive breeding program. This is a far cry from success, IMO.
If state law allows captive rearing, I don't see any harm in trying it. However, past results don't bode well for the success of the endeavor. I could see captive rearing and release being used to try and establish new populations in areas where habitat has been rehabilitated. However, I'd hate to see them dumped into prime habitat as a way of "keeping bird numbers up".
Captive reared birds don't survive well, and when they do survive they don't reproduce well. That pattern has been pretty well established.
