I have sheep, perhaps that makes me a shepherd but I have to say I really enjoy working with them. One thing I like about the sheep is they make me more active. I actually like scything grass daily for them which I throw over the fence. It is interesting how they come to expect it, and complain if I am not keep up.
The lawn needs cut anyway, and they love the short grass that isn't more than two weeks old. Also, areas of the garden that get away from me just get cut and thrown over the fence, before I turn over the soil with a fork to plant again.
Lambs are incredibly cute, and older sheep make great food for our catfish. The catfish are a bit scary. Drop a dead sheep to the bottom, in two days, just bones. The workers won't go in the pond anymore...
Parasites are a big problem with sheep, but with crop rotation, we seem to have gotten a handle on it, and rotating horses behind the sheep.
Mutton is really our meat of choice, but now I am going to try turkeys with sheep.
And of course, sheep fertilizer is incredible for the garden.
