Thanks for the advice,A few times I thought she was going to lamb ie; finding a quiet corner of the field and lying down with head upstretched and thought just leave her for a while... came back an hour later and shes walking about the field no bother.... By my calculations even if she was tupped on the last day before removing the ram she should have been lambing Week Ending 27th March. She was scanned with twin lambs and her elder has formed and her vulva has been pinkish for a few weeks now.
This is my first time lambing and so far all gone very well ... just a bit concerned about this one ... but maybe its quite normal??
