The lambs need a wee while to recognise mum too, our lambs were all confused at first, some of the mums are so alike. For the first 3-4 days I have found that the lambs are just like babies and just want to sleep a lot, wake up, have a feed, a little wander, then fall asleep again. In fact our Soay and the 2 Castlemilk Moorit ewes (all first timers) pretty much didn't move about at all in the first few days, just stood about with their lambs in more or less the same spot. The North Ronaldsays are bold as brass however and after day one it's get up or get lost, their lambs cosily together and not running after mum. Funnily enough I looked at the Soay lamb this evening, it was the second last to be born but is the biggest of them all - I still haven't seen her feed it!
