You can keep up to 10 goats per acre if you are feeding them. I used to build 4' high, 4' wide, by 8' long shelters in each pasture. I had a barn, but only used it in winter for kidding. Goats hate to be wet and easily contract pneumonia which can kill them quickly. But they are great animals, so much fun.So cute! Makes me want some goats. Do you know how many acres you need to keep goats in, and what kind of shelter you need (in Minnesota)? Do you need a real guy barn for them?
