Black spots on roosters faces

[Florencehb]

I have 5 roosters and they all have recently gotten black spots all over their faces and crests, one has also recently passed away, I don't have a clue what this is caused by or if it could be a disease and an issue to the rest on my flock. If any one has any ideas please help me out! I have attached a couple of images but in real life they spots are darker in color.

Off topic and asking in the gentlest way... is there any mold in that pile of compost?

Nope, none of it was moldy its just the lighting as it was starting to get dark when I took the photos
