How old does a baby yak need to be to stop there fathers care?

A baby yak, or calf, typically becomes independent at around 6 to 12 months of age. During this time, they gradually transition from relying on their mother's milk to foraging for their own food. While the mother provides care for up to a year, the father's role is less involved, and he may not actively participate in the upbringing after the calf is weaned. By the end of their first year, calves are usually capable of surviving without parental care.
