We have a six foot tall, wooden privacy fence around half an acre. The fence isn't in amazing shape, but we have fixed it up well enough that our two 80 pound dogs can't escape. There are no gaps, just a few places we need to resupport with concrete because it leans a little. (We just bought the house, the previous owners decidedecided it would be too expensive to pour concrete around the posts...gahh!!) I was planning on dividing the yard in half with horse fence and then letting the goats live in the back half and letting them in the front half when we can supervise. However, I read online that goats have been known to climb wooden fences. I've made sure there was nothing near the fence that would enable them to jump over, but could a ND get over it anyways?
