Well they do grow grass, but as far as I know the grass will only grow when you're within certain proximity to it. FYI, sheep will keep eating grass, even when they are ready to be sheered. I have a sheep pen with 13 sheep in it (maybe about 7x14 in size, they always have fleece and some patches of grass because it's near my home where I spend most of my time. My small remote pen of 3 sheep rarely had grass or fleece, so I moved them closer.
