3 week old black sex link and black astralorp

[AATH]

First Pic is black astralorp. Judging by the hundreds of pictures I've looked at I think at 3.5 weeks it will be a pullet. (I hope)

Second pic is black sex link. I know it's too early to tell but there was no white spot on head just this brown spot. These are the two I'm worried will be roos.
Anyone have experience like this and have an early guess?

Both look like pullets so far. I’ve never seen a black sex link with a brown spot on her head, so I’m curious to see how she develops.

She lost the brown spot on her head
