I went to the scanner you recommended Anne, Archie forgot his second name but a farmer from Falkirk area, his son used the sheep scanner in his garage and is a lovely chap, his son did it first and said more than 10 so pretty close as we had 11, then after not near, we went to his dad the last time at the farm...........never bothered this last litter although he is nice and its was only £20......I suppose it can be hard to actualy count them all as they wriggle and some will be hidden behind others......I go past his farm every weekend as Steve works near there!!
