This is only my 2nd year of having a mineral site, so I am not at all an expert. Last year I started my site with some feed mill recipe mineral mix. I started it the first week of April 2011 and the deer hit it right away gradually tapering off through the summer. I got a couple of bags of Monster Raxx from Pat Howard and mixed them in. I immediately tripled my pics. The deer were hitting it consistently throughout the fall. I refreshed the site again the first week of April this year and put the cam up. Week 1 - 126 pics, week 2 - 119 pics, week 3 - 102 pics and week 4 - 197 pics. Things I have noticed: 1) Deer LOVE Monster Raxx! 2) At the start of April, both bucks and does start using the minerals. 3) Mid month there is a bit more doe activity. 4) End of month, some bucks but mostly doe activity. The bucks are still there but the does are really hammering it. I'm assuming it has something to do with them preparing to deliver their fawns. I am anticipating heavier buck use during the coming months when antler growth really starts kicking in. What are your thoughts and observations?
