In my experience, pen raised birds hold much tighter than wild birds. Depending on the operation's flight pens, some also don't fly quite as hard/fast. Doesn't mean they are any less fun to shoot though.
So Dak Pheasant Numbers That article makes a good case for using pen raise pheasant as a way to protect the wild birds from too much hunting pressure.
The other interesting aspect of this is pheasants are the same as hogs... an invasive exotic species not native to the US yet we treat them as a native game bird.
Looking at the history of the 'American' pheasant you would be hard pressed to say pen raised birds dont know how to survive in the wild since they were a majority of the original breeding stock here which eventually led to 'wild' populations.
As noted there were releases of wild pheasants from China in the late 1800’s, but the foundation of most wild bird populations in the U.S. derive from those English game farm importations.
