My youngest Pied Royal Purple is already huge now, at almost 2 weeks old, so I couldn't get a pic of the flight feathers growing in like I was hoping, cuz they are already grown in, lol. I looked thru all my pics of all my Pied Royal Purple keets and I can't find any pics that show the baby feathers clearly enough either 
But here's a pic of a young Pied Royal Purple before feathers showing the narrower head stripe area, and a bunch of pics of older Pied Royal Purple keets that show the white flight feathers and narrower head stripe areas pretty good too. (Sorry if I went overkill on the pics, lol)
If I remember right, the keet on the far left in this pic turned out to be only a little bit Pied (and I sold her)
This is my youngest Pied Royal Purple I have right now... he's growing fast.
