Hey there. I think it might surprise to know how many mature deer can occupy the same area. Truth is, I don't know damn thing about that though. But I will say that certain areas with high numbers of hunters and hunting pressure, i.e. deer harvests, don't exactly help out the "mature" deer populations.Remember, if given the opportunity, even a spike buck canbreed a doe.Maybe your herd is just younger altogether. But there's gotta be a couple big boys in there.
