This plan will work with good population mgt. ! With feeding and those #s of LMB the first 3 years should be good. It will be managing the population from 3 yr out which will take some effort but is doable. This 3 yr on mgt. aspect is true of all LMB/BG stocking methods.
I would make one suggestion on initial stocking. I would find and stock 30 4-6 inch CNBG (50/50 male/female) along with the initial CNBG stocking (1000).
