Was wondering if there is a way to tell the sex of my baby pearl cockatiel.The breeder said both parents looked like normal greys with a little yellow on them. My avian vet said I have a pearl pied. It is just 12 weeks old now. I know the only true way is by dna. Heard something once about if the mother was a pearl then the baby would be female or male, or if the mother wasn’t a pearl then the baby would be one or the other but I can’t remember where I saw it at and was wondering if that is even true? Thanks!
