Looking for some input from some experienced free rangers.
I live on 3 acres in Ohio (zone 5). We purchased the property last year and it is very open and I have been planting like crazy. It is currently WAY TOO OPEN to free range, my chickens would be picked off by the neighborhood hawks in seconds but as my trees and shrubs fill in I would like to start free ranging. The final coop will be 8x8. Ideally I would eventually love the property to be fully fenced with a hotwire at the top and bottom (we have some crazy coyotes).
My question is, how many birds per acre is a good number so that they are not crowded, able to forage well and don't turn the yard into a barren wasteland. I am planting many species that will be wonderful food sources (viburnum, winter berry, mulberry, oak, elderberry, hazelnut). I am also trying to get a good mix of summer and winter cover for the birds with evergreens and deciduous plants.
I have been leaning toward large fowl so that they don't jump the fence into my neighbor's dog's jaws. I was also going to have about 4 or 5 Magpie ducks.
I'm just trying to get a good idea of a ballpark number - chicken math is hitting me hard and I LOVE hatching eggs.
So what number do you all find manageable on nice Midwestern property that is green from April to late October. We don't normally keep much of a snow pack, just the month of February (except last winter which was crazy!)
