I have already settled on 2 nigerian dwarf goats for milk, after hearing all the good things people had to say about them. After all the people who said that cows take up too much room, get goats, cows are dirty, get goats, cows give too much milk, get goats, I really couldn't overlook the pros of goats versus cows, even though ( don't let my goats know this, haha) I like the look of cows better. I was just curious, thinking, how much space do cows really need? Small breed, like dexter. 750 lbs max. How much space, dirt lot with all feed provided, would they need?
