Eyes are one the difficult thing to animate.
Thus, I want to control it by utilizing a bone contraint - Track to.
The problem is every time I put the constraint - track to on the eye ball to a bone positioned right in front of it. It moves from it's default position, almost out of its eye socket.
After constrained
I have checked that the eye bone itself doesn't move or rotate. So why the eye ball move?
Is there anyone can help?

Are you sure you don't want to use a different type of targets instead of bones/joints for the constraints? It's possible bones could be exported with the rest of the rig, and you'd end up with a bit of an issue there, with extra bones in the rig. Targets that aren't bones would probably be a bit safer to use.
It could matter how the bones were copied (if they were). If they are standalone copies it shouldn't matter, but if they're set as parent-child (or set as such in the joint hierarchy - you may want to check that), the eye could for some reason be following the initial move of the child, which explains why it moved when you linked it. When you then move the child bone, the eye moves even more. The eye set to follow the parent wouldn't move because the bone hasn't moved from its initial position. Or some variation of this, anyway.
Other than that, it is a bit difficult to know what's happened without looking at the file.
