Hi there,
I have a 14 acre small holding, we keep shire horses and other breeds mainly, but I do have pigs (large black & Gloucester old spot) sheep are arriving in spring I only ever take on orphan lambs as they are free or very cheap and you slaughter them in the same year so no shearing, breeding, having to keep a ram etc. I also have ducks chickens dogs cats ferrets etc!
Pigs trash your land, you will need to rotate where they live in an ideal world. and cost a small fortune to feed!
A house cow or dairy cow …..there isn’t enough room for! So do not listen to the above!
