I guess it depends on how you read the entire post. For starters, I doubt people raising a huge amount of penned birds on a pheasant club are using a tin can to feed them. But I don't know that since I've never watched a feeding cycle. I honestly don't know if you could coax a pheasant to come up to you looking for feeding like a horse or dog, etc. All of the birds I've seen on clubs seem pretty wild and didn't want to be anywhere near people or dogs. So I don't know how success that tactic would be or not. Your time on pheasant clubs may differ. Also, I considered large pheasant club operations and not somebody raising pheasants in a chicken coup on their own property. But you might have different personal experiences.
When I read the rest of the post, it looked like his lab was finding and flushing birds. Just like hunting on a pheasant club. Or in the wild for that matter. Maybe you just saw something different in his post than I did.
