I ended up giving the little ewe lamb to a great couple who live north of here. They are raising her as a bottle baby (feeding her using lamb milk replacer and a bottle). It seems to be a match made in heaven. They've fallen in love with her, and she is thriving. They've named her little Sierra. Pam kindly sends me updates and pictures. Wow, is she one adorable lamb.
