I have two percs. Each of them has only two stripes; they are missing the tail stripe. Last night I noticed a rather large dot on the tail of one of them. After a moment of worry, I realized it is the same shade of white as the two stripes. It is also surrounded by the same shade of black as the stripes.
Question: Is my perc growing a 3rd stripe?
