Goats are good for grass cutting. I think sheep may eat more roots so goats are better (reason for cattle/sheep wars). In the bay area hills a lot of homes have huge hillside yards. And there are some people that hire out goats to trim them.
That’s our yard! We had to get a four-wheel drive tractor just to mow it. I remember that about sheep now, probably from watching Bonanza and gunsmoke. They can pull out the roots and then there’d be nothing left to regrow. So I’ll definitely do goats instead.
But first, chickens!
