That actually does remind me, I bought two normal het pied females from a local breeder who seemed fairly new to the hobby. She claimed the entire clutch came out as females.
Decided to pop both of them a few months later, and discovered one was actually a little boy. Not too big of a deal, but it did throw a bit of a wrench into my breeding plans.
I wanted to raise the two up, and get a visual male later on.
Now I’m contemplating getting a visual pied female (maybe a subadult) to breed to my banana het pied male I just got. Would give me a decent chance at banana pieds
