Another aspect to "feeding" anything (from a stationary "feeder") is increased predation of whatever is eating the "feed".
Those who think they would find the evidence of this carnage are mostly mistaken. Bobcats, dogs, and coyotes can quickly figure out that a feeder location makes for the perfect "ambush" location. These predators will not necessarily kill their prey in front of your trail cam, but often on just close-by trails.
Then they may just walk off with their prey (such as fawns & turkeys), consuming it elsewhere.
Think you can find the evidence of a fawn that has been ambushed near your feeder, then eaten by a coyote or a bobcat? Think again. You usually will note nothing, other than wondering what happened to those fawns.
More deer under 6 months of age die annually than any other age group of deer. How many bones have you ever found from dead fawns? If killed (or found dead) by a coyote, you can expect no evidence that a coyote consumed it all.
Worse, it is the male fawns that get preyed upon at a higher rate, mainly due to their greater curiosity, often just walking towards danger.
