BAITING REGULATIONS
Use of bait - which includes grain or other feed placed or scattered as to attract turkeys – while hunting is illegal.
An area is considered baited for 10 days after complete removal of the bait.
A hunter can be in violation if they take or attempt to take a turkey by the aid of bait where the hunter knows or reasonably should know that the area is or has been baited.
It is illegal to place bait in a way that causes others to be in violation of the baiting rule.
Mineral blocks, including salt, are not considered bait, but mineral blocks that contain grain or other food additives are prohibited.
It is legal to hunt over a harvested crop field, but it is illegal to add grain or other crops, such as apples, to the field after it has been harvested.
Manipulating crops, such as mowing or knocking them down, is not considered baiting for turkeys.
