Final answer:
The ethical approach is to respect the neighbor's no-hunting policy and not attempt to lure the turkey onto permitted hunting grounds.
Step-by-step explanation:
The ethical decision in this scenario is to respect the neighbor's prohibition on hunting on their property. Even though you have the ability to call the turkey over the fence, it is important to practice responsible hunting ethics, which means respecting property boundaries as well as local laws and regulations. Attempting to lure the turkey onto the property where you have permission to hunt would be considered ethical hunting. Nonetheless, if the turkey remains on the neighbor's land, where hunting is not permitted, you should not attempt to influence its location with calls or other means.
