I was just given a 6 month old greek cheek conure. They have never had it sexed before and I would like to know how you can sex it. Can it be done by coloring or size or does it have to be vent sexing like chickens and ducks? If so would i have to take it to a vet to have it done or is this something I can do my self and some one could tell me how to? Thank you for any help.
