For most people, dedicating time to hunting, as well as, rod and reel fishing is not an efficient use of their time. Hunting will be an opportunistic event while you are doing other things. Snares, traps, set lines that can catch food 24/7 would much more efficient needing only to be checked once a day and not, necessarily, your prime workers or security people. Small game and fish would be the major protein supplement. A few years back, we set a night game camera in a clump of trees at the edge of a field a little over 100 yards from the house. There was a pine wind break just back on the inner perimeter fence. A little salt and a few handfuls of corn where set out and I was amazed at number of critters that came for a hand out. Several deer came, a bunch of rabbits, a small flock of wild turkeys, several raccoons, a couple of red fox and even a few stray chickens (from my neighbors). All this was at dawn, dusk or the dark of night.
Conclusion:
• The game is out there and willing to come in close.
• If you are going to plant corn or grains, they will come to eat it.
• Your security is going to have to oversee your food crops to protect it from 2 and 4 legged pilfering.
• This provides an opportunity bag some game and vermin without expending additional man hours.
