At pheasant release hunting sites the birds are released a day or two before the hunt. They don't flush like wild birds, but they are not in a box.
My personal ethics require me to search for wounded game until I find it, or determine I won't be able to. This takes hours of searching. I have spent up to 4 hours searching for an elk someone else shot poorly. We determined it survived. A month later I saw that same elk, another hunter harvested it. We each have to set our own limit for "reasonable effort".
You can't fix stupid....however ignorance can be cured through education!
