We had Saanen dairy goats for over 25 years and I made hundreds and hundred of pounds of cheese, lots like what the Grandfather made. Other kinds too but that was my favorite and the easiest and the most versatile.
Are goats easy to keep? I’ve only been ambitious enough to think of chickens, and maybe one of the miniature cows - like a Dexter - as a retirement hobby. But with the mini cattle, you’d have to be someplace where others are raising them, too.
