Well it all got interesting, I let them out and new Mum of twins just waltzed out and ran straight to her old Mum (who is expecting!!) No interest in lambs! Poor lambs left being (not too aggressively) butted by others as they very confusedly tried searching for Mum - who wasn't in slightest bit interested in baaing back at their calls!
Cue panic from me, and thinking quickly on spot I put the expecting Mums in a separate field, put new mum with twins back in barn and let my other mum out first who set an exemplory way to behave to her lambs! I then let mad mum back out and without attention of her Mum and the others she seems resigned to behaving like a Mum and today has seen good bonding and bleating from all concerned.
Trouble is I've now got expecting ones in another field away from barn so haven't been able to get them in tonight! And god knows what mad mum will be like when she sees her mum with lambs!
Sheep psychologists anyone?!
