The ewe is a mule of some sort - the ram was a beltex (think he is now a jalfrezi in Birmingham somewhere). Thanks for the reply - I tried to entice her into the shed earlier but the two rams squirmed like mad when I tried to use them as a 'carrot' for her and she just went mad, couldn't work out where they were (despite them being in front of her) so I figured she was best left. The other ewes, after an initial inspection, seem to be leaving her alone.
