What is a rejected sheep from the flock called in Australia?

There isn't a specific term in Australia for a rejected sheep from the flock.

Here's why:

* Sheep are social animals: They naturally flock together for safety and comfort. While there may be individual sheep who are less social or have issues fitting in, they wouldn't be actively rejected by the flock.

* Farmers manage the flock: In a farm setting, the shepherd or farmer would likely intervene if a sheep was exhibiting unusual behavior or seemed to be struggling to integrate.

Possible terms used to describe sheep that are different:

* Outcast: This is a general term for a person or animal that is excluded from a group.

* Lone sheep: This term is often used for sheep that stray from the flock.

* Problem sheep: This term might be used for sheep that are difficult to handle or that cause issues within the flock.

It's important to note that these terms are not specific to Australia and are used in other parts of the world as well.
