Black on combs - Blue Copper Marans chicks

[nmunroe]

Hello,
I have 3 blue cooper marans chicks that are approximately 5 weeks old. I noticed yesterday that 2 of them have black coloring on their combs. Other than the comb color they appear to be behaving normal. I had read that black spots I the comb could indicate an illness. I am curious if I should be concerned, or if this is a normal variation of this breed?

Hi there, sorry no one was able to respond, how are your chicks doing?

They are doing fine. They still have the black patches, but they haven’t changed. I jut assumed that it is part of their coloring.
They haven’t shown any sign of health problems.
