We have about 1 acre of sloping grazing land on which rushes seem to be taking over in patches, and approx 1/2 acre of copse with mature trees and grassed areas, both well fenced and watered. We would like to keep a few pigs to bring on for the freezer but help would be appreciated in choosng the right breed and how many, also would the pigs clear the rushes as better drainage would be difficult.
