Never mind the cows. They are big, can’t hid ‘em and you need a way to preserve all of that meat. Go with rabbits and chickens. A rabbit is eatin’ size in 8 weeks, they take up very little room and it doesn’t take much to feed them. Chickens can do a lot of foraging for themselves and you get eggs.
I agree with you my fellow Scotsman! We had rabbits and chicken growing up but I like milk too! You can pressure cook and can the meat which I have done this year and it is awesome. I actually had lamb chops for the first time in my life a couple of nights ago. It tasted like some of the best beef I have ever had. That appears to be an option too.
