Welcome to the forum. I think you are in good shape with your plan. Most articles that address supp. feeding provide that one feeder will only service at most 3 acres for BG. That is because they (BG) will not travel far to engage in supp. feeding. The smaller the BG the less distance they will travel to get to the feeder and many will not swim out through open water. I have seen info that says they will stay with in 300 ft. of feeder. I agree with Bruce that even if feed to satiety they will still forage on their own to meet food demands.They eat small amounts often and will forage between supp. feedings. But given that you are only supp. feeding I don't think you need to worry about BG being lazy. You should get added growth and reproduction from your plan. Keep us posted. I will look for additional info and post as found. ewest
