Gulf Coast
Native sheep are supposed to have good feet and good tolerance to Barber Pole worm but I don’t have any personal
experience with them. My Icelandic’s have good feet but not good tolerance to worms.
But I think the most important thing is keeping their feet trimmed especially if it’s wet. When there feet get overgrown muck gets caught in their feet and causes problems. Trimming every 2 months is probably good
enough. And a dry place to hang out helps too.
Good luck with your sheep adventure.
