Yes, but is it a good investment, compared with any other investment you could make, that's the question!
I'd have thought that if you want to make money, there must be more lucrative and less risky ways to do it than sheep farming, particularly without any prior knowledge of the subject.
Why are you interested in this as a business Reza? Is it because you fancy sheep farming and want to know if it could be profitable, or is it purely because you want a financial return on your investment?
