SHeep , sheep, and sheep. They will eat anything, even your prized daylilies. They are EASY to keep in the fence, and are much neater pasture keepers than goats. Sheep eat the grass at the ground,, where goats nibble the tops off. I have a sebbie goose that eats grass ALL the time, but at the rate it produces poop, I don't need more than 1 LOL!!!!
