How can a Zebra fit in?

Question

There's this horse stable in my area and it consists of ONE zebra, ONE bull and some horses.

Knowing that zebras normally live in a herd, how can it fit in to have a bull as a friend? You know, just the two of them, chewing on grass the whole day together!

** I don't think the bull charges the zebra as they live in different ranch.

Answer 1

They are both social herd animals, in the absence of their own kind they will hang out with no problems.  We had a horse, a goat, and three geese in one pasture, they got on just fine, and even stuck together when the dog chased them around.  

Answer 2

most of the zebras i have hung out with were pretty wise.

the zebra you are referring to probably realizes

his/her station in life, and will assimilate with the others.
