My buck pen is probably 40? feet away from my doe pen. I used metal poles (can be bought from tractor supply), and wielded wire (also from tractor supply). This cost about $150, and it's 1/4 of an acre, perhaps more. Fo shelter I bough an extra large, super durable tarp. Which I tied around a round-bale feeder ( We took it apart, laid the two sides to make arches, and then put the tarp over it), my bucks do just fine in that. They've lived in it for about 5 months now. Just a cheap suggestion ;]. Getting the wire up was hard, though.
