Yes most likely. But they can and do survive out there. I have a couple in my pen now. A gal we buy birds from used to haul birds to a so called "wild" bird hunting place in SD, she had to deliver them in the dark, go figure. But any way she always has these mixed in. After intermixing, some will have no rings, some will. They are cool looking. The hens are dark brown.I had some of the training hens get away months ago. And still see them from time to time. They get more jumpy each time. So there is a chance as well this could be a wild bird raised from released birds in the past.
