no doubt that yotes are killing fawns, penn state survey or not.the biggest predator is hunter.when all this doe killing started,thats when deer started to disappear.i agree, i never saw so many yotes as i do now, never. as for dens,i dont know but many experts on that here.couple years ago you could shoot 5 deer.thats terrible.i saw more doe killed 2 years ago ,now no deer. it is overhunting, no doubt about that and yotes dont help what is left.we need a new governor, for sure.
