Katahdins and Barbados Black Belly sheep are naturally polled. I raise both of them. The Katahdins are much easier to handle. The Barbados are much hardier though. I have dewormed the Katahdins twice this summer, but have not dewormed the barbados at all. Their eyelids stay nice and pink. They are SO flighty though. Don't plan on handling them much....it's almost like owning wild animals. But they are tough as nails, don't eat much, don't need dewormimg, lamb easily and are produce very lean meat. The Katahdins are so gentle and easy to handle but they do need more maintenance.
