Hi Water Buffalo Farmer,
I just started this year and had 6 Crossbred ewes which were covered by a cheviot tip (tup). When scanned 1 were empty which i was going to replace but decided this year stick with what i had so i sold the two empties and kept the 4. ( wishing now i had bought a few more.)
But as they say creep before you walk s i am very satisfied ( So far)
