Goats are eating machines. They are designed to eat coarse greens. Stuff with bulk. Where to put all that food? In their complex bellies. I take the kids out to graze and I can actually see their middles expand. Here is Caper. He is not yet ballooned out to full capacity.
Note the stripe along his back. This strip of long hair is as expressive as a dog’s tail. Excitement makes it stick straight up like a mohawk. Worry makes it quiver. A content goat’s strip is flat. I have goat books, but none mention watching the mohawk, so it was a surprise to me.
