Here is a video of me rooing Gilroy Corrine 's ram that I leased. He was really easy to roo and reminded me of a Soay as far a rooablity and fleece type. Some sheep will roo part of their fleece but not all. (All of my rams rood parts of their fleeces.) I rood one ewe and she didn't roo as easily, but neither Gilroy or that ewe's fleeces need any cutting.
I have around 30 Shetlands to shear or roo still. Some have not gotten the rise enough to shear yet.
