Would be fun to see, but I imagine it comes down to expenses vs. profit. They probably figure the cost in time and money and gas to produce small game hunts on video wouldn't justify what they'd get in return in the way of sales. Plus, if you think about it, all the game they video are species they make calls for (Deer, Elk, Turkey, Ducks, Predators).
After all, they are Primos Hunting Calls.
