We have 1 acre in front of our home that i would like to fence off for a goat pasture. I would like to have a Nubian doe and a wether. Hubs and I have agreed on fencing layout and a portable 2-sided sun/rain shelter to go inside the fence. We're looking at putting up a divided 12' x 12' shed-roofed mini-barn; 1/2 for a night shelter and 1/2 for a milking area/ feed storage. Because of our property layout the barn area is across the driveway from the pasture. I think i need an attached 10' x 10' pen with a door from their sleeping area to the outside. Do I need an attached pen, or am I making this more complicated that necessary?
