We have two sheep, but they are not milkers. On the long run we might swap them for goats. Our land is not really big enough for neither of them and we have to bring in feed. While I know that sheep eat leaves they might be happier with hay, which we would either have to mow ourselves and dry (we have a moist climate) and store. Grass does not grow here in winter it can get down to -5°C at night. Goats eat more, but they might like more of the environmental weeds (maybe cotoneaster?) and I imagine that if we would plant shrubs like tree lucerne we would harvest more per m2 than with grass. Goats give more milk and they might be easier to milk, but sheep milk has more fat and is better for cheese and cream(?) and butter(?). But the main thing is the feeding question. And where do you store all this hay??
