Last year we had a few heifers to have calves by their sire. Some were fine and a couple were not. One was born with its front legs literally backwards is the best way I can describe it and one leg was actually bowed out side ways,
Another calf was kind of like what your video showed. That calf eventually grew out of it enough that it was barely noticeable at all by weaning time.
This year the first mentioned cow had a calf by the same bull before we got him sold and that calf is as far as I can tell physically ok, but slow not in movement but in other ways.
The other cow had a calf by a different unrelated bull and her calf is perfectly fine this year.
This is the last years calf that pretty much grew out of it The second picture is when he was a day old you can see him standing odd with his front legs.
The first picture he is a little older
