As stated by RBST
The Boreray is a very hardy breed and will do well on sparse grazing and is able to cope with most conditions. Anecdotal evidence suggests a high level of resistance to foot rot and flystrike. The breed is long lived, with ewes often lambing into their teens. The average lambing percentage of lowland flocks is around 140% (meaning each ewe averages 1.4 lambs a year) however in the feral flocks the average is less. The breed experiences very few lambing problems and lambs are small and lively. The breed can shed its fleece although not all animals do so.
The Boreray’s extreme hardiness makes it a useful breed for some grazing sites where other sheep would struggle. However numbers are very low so this market hasn’t been fully exploited.
The Boreray has an excellent flavour and in common with most primitive breeds is generally slaughtered as hogget or mutton for a bigger carcass. With such a small population there is little evidence of any crossbreeding programmes using Borerays.
