Those birds are good looking with healthy plumage and long tail feathers, that tells me that those are wild birds. When you are hunting the vast open fields and plains you can tell the difference between a recently released pen raised pheasant and a real wild pheasant. The real wild pheasant who hatched in the wild and has been running on the ground since he came out of the egg and chased by predators from day one, has a well developed cardiovascular system and flushes fast with a vary rapid wing beat and some times flushes out of gun range. On the other hand, the fat no exercise, often poor plumage (not all of the time) pen raised pheasant has a slow motion wing beat and flush. Some times a vary easy shot.
