We are in a totally different situation. With 5-10 acres, you couldn't do
much of anything here. Especially in the north country where I am.
If you ran one horse or one cow on 5 acres, you would be purchasing
feed for more of the year than grazing time. Basically you would need
a feedlot situation if you want to run any numbers at all.
I would suggest you find an ag oriented agency there that can help you.
I'm sure there is some information available if you look around.
Do a google search. We are used to dealing at least in hundreds of
acres, if not thousands.
Good luck!
