I am thinking about fencing off my back 2.5 acres and building a barn and getting some goats. I have 30 chickens already, but was thinking of hatching like 50 or so and making a roost in the barn and letting them free range all day. I wouldn't want to feed that much because 80 chickens to feed is a lot. I free range about 20 of my chickens and they just eat what they can get each day. They don't go that far out to find food like 20 yards from the coop. So my question is hoe many chickens could i put back there to just free range and find what they can eat. The field is just open no trees just a bunch of weeds. This would just be for the summer and spring and a little into fall for eating purposes. I would butcher all of them by winter.
