Welcome to you and Tank - we have a sheep named Tank! He's called that because he refuses to move when he's standing in our way! How did your boy get his name?
Welcome and kudos to you for helping with rescues! It sounds like Kowboy was a great introuction to the breed. I'm sorry for your loss of him and Indy. this is a great place to share and keep memories alive. I'll keep my fingers crossed for a speedy relocation back to your family in CA!
