What does it matter if one occurs naturally, if it’s not instant, or if it’s dumped out of a bag? You are hunting over a food source regardless.
And everyone that fools with feeders will tell you it’s not instant. It takes a buck 2-3 years at least to get comfortable enough to eat from a spinner feeder. They usually have to be raised eating from it with their momma. Well that’s a four year investment.
Deer wants food, you manipulate the environment to provide food, shoot deer when he comes to eat. It ain’t rocket science guys.
It’s all manipulating the deer’s environment to be able to kill him. Just be a someone manipulates it differently than you doesn’t mean it’s not manipulation just the same.
Can you fertilize naturally occurring food sources and it still be a noble way to hunt?
