Corn feeders are the worst thing to happen to turkey populations.
How so ?
I've hunted a couple of ranches several hundred
miles to the west of here that didn't have much of
anything for the game to eat. The one place was
2 sections IIRC, and there might have been two
dozen oak trees on all of it. The rest was spindly
mesquites and prickly pear and probably 3 blades
of grass per square foot. What little food there
was had cattle and deer and swine and game
birds competing for it. If not for the lease hunters
feeding corn and protein and the ranchers
feeding the cattle, it would have been a scorpion
and rattlesnake ranch. There were a gazillion
turkeys ( all Rio Grande) and I'm fairly certain
that they were pretty grateful for the corn that
got slung out of the feeders every day. I know
the deer were. Seemed like every cactus pad
you'd look at had several deer bites out of it
