Seeing that brings back a wonderful memory. When one of my uncles ewes refused her lamb, it was given to me to hand-raise. Snowflake was very special and would stay right beside me wherever I went. I long to get that close to a lamb again and envy you the opportunity.
Ah, that's the life. Good for her to know how to be comfortable!!! And yes, you are going to have a hard time convincing her that she is a sheep and needs to be outside with her own kind! Good luck!
