This goes deeper. There were two the first a black and white marked with the 7 born on September 20,2014 the second 5 days later. September 25, 2014 which was the date of the jewish new year Rosh Hashanah. Just for fun the customary greeting for that day is Leshana Tovah Tekatev Vitechatem or May you be inscribed and sealed for a good year. This calf is certainly marked like a seal.

I can't watch the video but I would be curious to see if we could get at least an approximate time of birth. I want to know if it was somewhere around the time the shofar's were blowing or during Tashlich prayer service when sins are symbolically cast into the depths of the waters.
