There isn't an exact policy. The oldest wiki is usually the one that goes in the infobox, mainly because any created after that would have been a duplicate that could have been avoided.

But....sometimes the oldest is abandoned and has very few pages, in that case it is best to merge the two and pick the one with the best URL (xxxx.wikia.com) name as the primary. For the time being it can be added to the "other wiki" section.
