Hi - we regularly have to check our fencing as the wild boar are constantly making holes in it. We have neighbouring sheep and I wouldnt want another ram getting in and mating with my pure breeds. I dont expect my neighbours would be very pleased either. Dont think there is a 'morning after pill for sheep' correct me if I am wrong. lol Thats the biggest problem with sheep - the grass is always greener on the other side. We have 22 hectares of grassland and trees so if they get out they can wander a fair way - luckily they will come to a loud shout and a bucket.
