I have a sincere question for you. Which breed of goat would have the best chance of survival in six or seven months of winter with temps colder than twenty below and winds commonly over 80 mph? ...looking for goats of a tougher kind to clean up some very high pasture (over 9,000 feet) with snow drifts often over four feet (eight feet one recent winter). They would have a long shed with straw litter for getting out of the wind, and that’s about it (and two layers of snow fence just to the west of the shed).
Try mountain goats.
You definately don't want angora's they eat a lot but also need a lot of care that other breeds don't need.
PS they originate from Turkey...
