I want to maybe get a pig this summer but I don't know very much about raising them. How much space do they need in their pen/stall??? How much space do they need outside in their pasture??? How much water do they drink a day??? What do you feed your pig??? I might be getting goats.....so would the goats be okay with the pigs/and as their friends??? If I had goats would I need to get 2-3 pigs or could I just get one???
