I don't have a seperate milking area, but bring them out of their pens across a small clear area, milking bench is half a pallet (No gaps between boards), which I than made narrower, 2 lengths of (I think) 4x4 wood raised it up a bit more. I sit on a little 'step stool' plastic buffet. Goats are tethered to a ring on the the wall, and don't get fed while milking, they get fed when back in their pens. (goats don't graze while their babies are feeding).
Lucky thing getting Golden Guernseys, I've admired them for years, went down to a show in Malvern, probably in the eighties, never did get one. I think quality has improved drasically since then :-).
When is she due?
