My goats are a Nubian/Alpine mix. They produce a fair amount of milk, are good browsers (they're part of our crop rotation plan) and a few shakes of a bucket of grain is all it takes to get them to come in. We have perimeter fencing as there are some things in the garden that would be poisonous for them to eat, and I don't want their snacking to cut in to our floral arrangement sales profit.
With a small herd of just 4 milkers (last springs' kids were given to another farm business who make money leasing goats as natural weed trimmers) they are incredibly friendly, like a strange type of dog. They respond to their names and love a good back scratch from their people!
Now if only the laws in my state (NJ, USA) weren't criminally restrictive when it came to selling raw milk products.. well, more chevre for me!
