Can anyone tell me if this calf is (mostly) pure Angus, or if he may be Brangus? We bought him at auction as a "black calf". He was really small, weighing only 62 lbs at a couple of days old. He is almost 4 mo. in this picture. It doesn't really matter, just curious. He is the one that is cryptorchid and someone mentioned that it takes Brangus longer to develop.
