I did that with a bird i was convinced had a spitzhauben mom. Turns out one of my other birds lays white eggs too and I didn't know 😅
It's possible some grow crests and some don't. As for the barring, a lot of my pheonixes grow those feathers and then grow out of that pattern when they're older...
I still can't see anything, but I'm not saying you're wrong. Might just be having a bad eye day again. Theyl l probably only have tiny crests if they have any. Usually chicks with big crests have those noticeably since day one (just look at polish and spitzhauben chicks)
