What calf?

Such as strong calf, fat calf, lovely calf, handsome calf, naughty calf, naughty calf and fierce calf. What can be used to describe the state or characteristics of a calf? For example, there is a fat cow in the neighbor's house next door, and it is being discussed to sell it for money. There is a naughty calf in my family who likes to make a mess of wild flowers in the field every time.
