That one spot of paper does look odd. I didn't notice before though. I'm pretty certain now they are khaki cambell also. They have lightened up a bit sense these photos.
Yolks?! In the photo they were standing in a combination of wood shavings and shredded paper because that's what tsc sent them home with. Lol. But most definitely not yolks.
These are right after making it home from tsc. They are all solid black with one light dot on the end of their beak. Except the one with the arrows. Still solid black but instead of the one centered light dot, it has two light spots. One on each side.
