i had mine scanned for £70 for 5 ewes, i was happy to pay as its very hard to get scanners to do small numbers
my only issue was that she got 3 wrong and i ended up with 3 sets of triplets rather than the twins scanned!
i had them on a feed regime for twins and they all turned out pretty decent so part of me was thinking not bothering this year, and using the same feeding regime,
i would have trouble if i had a single but as Wiltshires are very prolific id be pretty confident that i wont get a single
