Am getting 8 heavy brown egg layers, docile breeds. I live on 2 acre lot with open grassy lawn areas (no chemicals) and several hundred feet of moist bog (full of blueberries & raspberries in summer) leading to the edge of a small lake. Would like to let my chickens enjoy all this, but if I let them out of their fenced run to free range, will they stay reasonably together in a flock or scatter willy nilly all over the 2 acres? Do chickens follow their owners around or just do their own thing? I'm obviously new to this "sport" and have visions of chasing chickens through the woods to get them back in at night. Am worried they will roost in trees and get eaten by critters (coons, coyotes, etc. around here). Thanks for humoring a newby.
