DL, I'm an angus breeder i've herd of this happening before, personal havn't seen it but the answer to this is.... A Albino calf! It's that simple, instead of culling the white calf off someone played with them and started a "new breed." Now that is ver simlar to how Red Angus got it's start if you've done a bit of looking. The Reds were thought to be not normal.
#1 - this is not an albino cow - she has black around her eyes and pigment in her iris - albinism is characterized by complete lack of melanin

#2 - In 1808, Hugh Watson, the father of the modern Aberdeen -Angus breed decided he wanted black cattle not red - it was not that res was considered"abnormal" as you say but a personal decision
#3 - In 1889 the American Aberdeen Angus Assn set a course aimed toward creating a pure black strain of Angus and in 1917 they barred the registration of red animals (allowed previously)
#4 - in 1920 the Wisconsin Exp Station s published The occurrence of red calves in black breeds of cattle - "One more point should be emphasized, namely that the red individuals appearing in such stock (Aberdeen Angus) are just as truly purebred as their black relatives, and there is no reason why, in all respect save color, they should not be fully as valuable. The fact that they are 'discarded" while blacks are retained is simply due to the turn of fortune that black rather than red became established fashion for the Aberdeen Angus breed"
#5 - In 1954 ten individuals formed the RAAA with the goal of "making the Red Angus a useful breed of cattle through careful selection and recording of animals" - performance data was mandatory and this was the first association sponsored performance program
#6- 1980 "Modern Breeds of Livestock" -'In reality the Red Angus is not a distinct breed of cattle but is a selection for a specific color within a long established breed" and it was known for years that 2 blacks could have a red - in fact Hugh Watson knew this
So if you know the history of both the blacks and reds it is clear that black was selected for because of personal preference and that the founders of the RAAA had great foresight and were very successful in reaching their goal
