We sheared our sheep last night with a brand new lister clipper with the wizard blade. Our little girl jacob looks very pink along her spine this morning and I can't get close enough to see if it's color on the wool (??) or the skin underneath. We sheared in the evening so there is no way she got sunburned between 9 p.m. when I put her up and 8 a.m. when I brought her out. What happened?
