Salmon fav. very pale comb?

[Over_Easy47]

I have 3 rooster faverolles and this ones comb seems to be extremely lighter than the other two. Is that normal for faverolles maybe? Sick? I just don’t know what could be wrong

Age and hormones can play important roles in comb color. So can serious disease.

First, it would be helpful if you would tell us the age of this rooster. Then if you could describe his behavior, it will tell us if he's sick or not.

-Is he active or is he just sitting in one spot, not moving?
-Is he eating and drinking?
-Does he have normal poop or is it watery and greenish?
-Are his eyes clear and open and bright, or half closed and perhaps swollen at the rims?
-How is his breathing? Rattly or crackly?
