Is this normal?

I wasn't 100% that this is the right forum to put this,so my apologies if it isn't. I have 2 Silver Spangled Hamburg chicks that at first I didn't have doubts as to their breed as chicks cause they looked normal for their breed. But at the moment at 4 weeks old they appear more black than white without the spangling. Which, from pictures I've seen online,seems kinda odd since I was expecting white birds with black spangles!So I was wondering,if this is maybe normal for this breed to be late with their correct coloring?

Normal for young Hatchery quality (meaning they aren’t bred to the SOP) birds.
