First ole hat, welcome to PM forum. Give us some more info such as type of terrain where you hunt, size of fields if available, how much land do you have to hunt. Then give us a rundown on your setups. Are you calling upwind, crosswind, or downwind? How far are you from your vehicle? Are you calling day or night? When coyotes answer, how do you respond?
I'm pretty sure the excess food will attract coyotes and not keep them from coming to prey sounds. Fill in some blanks for us and maybe we can help.
