Do whitetail like alfalfa hay?
They usually tear it up
even if I have a lot of natural green growing, I still buy a square bale or two if its real green and spread it around the field and throw a pad or two in the feeder pen.
Piggies seem to like it also.
Buy a square bale make sure it is fresh and green otherwise they will not touch it, separate the pads put them around your hunting area if they like it then you have another attractant
