I look for juveniles that have almost no kok at all and hope like hell it doesn't over develop as they mature lol. No way to know for sure, but they don't all natually grow massively stupid kok. Mix of genetics and whatever they feed them over there to encourage it.Was not aware that they would not develop the bulbous head. How do you select one that will not develop that as they grow later?
Even finding a juvie without an already large kok is extremely difficult.
