10,000 Pheasants released for hunting season

[Catherine]

Ten thousand pheasants released for hunting season. That is ten thousand captive raised birds who are now being released so a hunter can shoot them. They wouldn't have the survival skills of a wild bird. These birds are being released to certain death.

I have a few questions that the article doesn't cover. Who would raise a pheasant like that just to send it out to be shot.
Who would want to shoot a bird who was lost and confused by its new environment. 
If they release 10,000 birds and there are twenty thousand hunters these are going to be a lot of wild birds that will die.

How can they hope to sustain the numbers when there are so many hunters.
