Foobar - There are already shedding black sheep, some easy cares do come out black very occasionally and I know a man who has used exlana rams across the last of his parents bwm (inherited with the farm) to produce a shedding back sheep.
R.E Shedding sheep and welsh rain . . . . . . . . the original easy care breed developed in the 60's were bred on Anglesey, and there are plenty of people (myself included) who run shedders in rainy wales!
All this talk of taste . . . . . . . . I honestly think some people are fantasists. . . . . although some rare and minority breeds give what is defiantly a different tasting meat, when it comes to most other breeds, there is far far more in the butchering, hanging and cooking that effects the taste than the ram used!
