I was about 12 i remember helping with them they were basically left to their own devices it was a really easy lambing from what i remember. The 220 lambs came from about 250 ewe lambs so they did really well considering. The lambs were slow growing and didnt make 40kg were all sold in january for about £10 over the weight (37kg lambs £47) which was bloody good back then. I get thus story most years off dad when were sorting ewe lambs out from the ram lambsSounds like fun!
