I also managed to catch #200 which is a HUGE brown lamb with a white face. We also gave her rear-end a wash as she seems to have some digestive problems. We are keeping an eye on her but it is almost impossible for us to isolate individuals and give them a different diet.
#258 also had a wash, she is one of the smallest lambs and most tame. She seemed to enjoy being made a fuss of.
#256, one of the black ewes has worked out how to get under the fence (but not how to get back inside). Then in the evening while we were making hay we found two of them in the main field. So, I have now piled birch branches against the fence to stop the sheep from crawling underneath. Once they've figured out an escape route, they don't forget it. It's very unlikely that they would wander off, but they get upset and noisy) when they can't get back in with the others.
