NEDOC, what you experienced with the birds is exactly what California experienced in trying to establish pheasants and turkeys. Pen raised birds didn't last a week in the wild. They didn't know enough to roost up off the ground in trees at night, so they got eaten. Only when they imported wild birds from other states did they take hold.
A friend was the person in charge of District 5 in California and that's what he told me.
