Ive been seeing deer pushing each other around for 2 weeks now. My trail camera pictures have bucks every night tickling the horns. Nothing serious but they are definately getting frisky, testosterone is building up!! I also have heard bucks grunting already and weve heard some light rattling in the field, again, not because the rut is here, but deer are vocal, and its probably just a dominance thing or something. But, I would say it cant hurt to do some light rattling in the next week. Deer are also curious animals, so maybe it could generate enough curiousity to come and see whos playing in the neighborhood.
