I would keep your cuckoo if I were you. Cuckoos are a work in progress, and if bred to the right mates, they will only improve. Regardless of whether its a male or a female, yours could still produce cuckoo chicks - a male will produce cuckoos of both sexes and a female will produce cuckoo males only. But a male can be single or double factor - if double factor, he will produce ALL cuckoo chicks, regardless of what color his mate is, and a single factor will produce about half cuckoo chicks. If you don't have a cuckoo mate, breed this one to a black. Or a blue if you don't have a black. A splash would work, too, but all the offspring will be blue or blue cuckoo.
But if you don't want to work with this gene, I'm sure someone else will, so I have no doubt that you'll be able to sell him/her.
