Build your goat shed tall enough that you can stand up in it. We made the mistake of building just taller than the goats with the first construction.
Overbuild your fences. If smoke can go through it, so can a goat. OK, small exaggeration.
We have one goat who will clear any fence up to 5 feet tall, but I don't think that's a normal problem. They will, however, not be contained by barbed wire at all. You need good field fencing with a hot wire at nose height inside.
Gates must be child proof, adult proof, clever monkey proof. They *know* what the gate is, and they figure out how to open them.
Keep your feed in a building that the goats cannot get into. At all. Ever. Keep the feed in barrels or something they can't open so that when they *do* get into the building they don't overeat and bloat.
