Key recommendations
- Shearing: March.
- Best months for crias to be born: Mar–May (breed in Apr–Jun).
- Heat precautions: Jun–Aug.
- Barber pole worm season: Mar–Oct — run fecal egg counts every 4–6 weeks in these months.
- Freezing nights: Dec–Jan — keep water from freezing.
- Vitamin D: winter sunlight is usually adequate at this latitude; ask your vet about dark-fleeced crias.
- Grazing season: Feb–Nov (about 10 months); feed hay the rest of the year.
- Meningeal worm: This area is at the western edge of the meningeal worm range. Risk is real where deer and snails share wet, wooded pastures.
- Selenium: Selenium levels vary across the state. Test hay or blood before changing supplements.
