If there is not a gender option on the website, that particular species is 'monomorphic,' which means we’re unable to determine gender without DNA testing. DNA testing is an additional $99 per bird to be tested. If you want us to do our best without DNA testing, just make a note in the comment section of your order letting us know your preference. Please note that if no DNA testing is ordered, we are unable to guarantee a preferred gender but will do our best. See our FAQs for more info.
