I am not able to figure out my cocktiels' genders

[Echo3]

I have 2 cockatiels, i think they are whiteface but a mix of something else as well. The breeder says they are a male and female, i can't really tell. The male has less tail feathers is a bit smaller, the female is a bit bigger and longer tail feathers and more crest feathers. Can anyone help me out?

The beak is also lighter than the female's

I'm not sure how to tell mutated cockatiel gender, but those birds are gorgeous! Have you tried asking in a parrot forum?

Do you have full body photos showing what tail feathers the suspected male has?
They are both whiteface pearls. the first does look like it may be a young male. With pearls the males will molt out the pearling and replace them with solid grey feathers, which appears to have possibly started. the females will retain the markings for life

The male has no tail feathers
