Jeff, when coyotes are run in high fence enclosures, they are not killed. This is a training exercise, and there are many culverts and such provided for the coyote to duck into when it has had enough. Fresh coyotes are brought in regularly.
Coyotes run outside of enclosures have no boundaries. They can and do run where ever they please. Catches result in only about 20% (or less) of the chases. Doesn't sound very productive does it? It isn't productive at all. It's not about killing coyotes, it's about the chase. Houndsmen do it for the chase.
Deer herds cultivated in high fence enclosures are more like cattle in temperment. They are conditioned to the smell and presence of people. They know where all the salt licks and food dispensers are located. They've been conditioned to abandon all caution. They will calmly approach a bunch of noisy, beer drinking, self-proclaimed "sportsmen" sitting on Barkaloungers in a blind. These deer would probably still approach even if these slobs were sitting at a card table in the open with the radio playing. There's no sport in this activity at all.
