Got my seeds ordered already.
You might want to consider a dairy goat.
My understanding from people who raise them is that they are easier to raise and keep than cattle. they are apparently hardier and less prone to disease.
They are also smaller, and therefore easier to literally push around if need be.
I looked at goats first. There were a few reasons I decided against them, but I know some people prefer them.
Dairy sheep seem to have all the advantages of dairy goats, plus a few of their own. Among other things, their milk is so sweet and rich, it’s like drinking ice cream!
