I like your thinking. I am familiar with whitetail Institute products and have used them in PA food plots. You cannot grow a 300lb Canadian buck but you can ensure your deer get supplemental nutrients that will give the bucks additional minerals to achieve maximum antler growth for your area. The does will lactate better also giving the fawns a better start to life. I see no down fall to your plan unless you stop feeding and then all that happens is the deer return to what they were prior to your program. Make sure that you separate the feeders out to minimize potential saliva disease type health problems. Good luck with your plan and keep us informed how things go.
The main 2 minerail site that are next to feeders and water tubs are over 1/2 mile apart and still not close to to where they can been seen.Except from our property,1 mile wide and 1.5 miles long
