Your use of the term "black sheeps" is offensive, and incorrect. In modern society it is normally used to describe a group member who is misunderstood because he is unusually intelligent, independent, or artistic. Technically it describes a person who refuses to conform to his families wishes. This is not always a bad thing. Firefox was the "black sheep" of browsers for a long time.
As a side note, the plural of sheep is sheep, not sheeps.
