Emergency, save rooster? Or put down?

Necrotic means dead. Necrotic tissue can often cause infections if left in place. If you've not got a vet, then I do recommend you get as much dead black stuff off as possible. His comb looks healthy, and from what you're saying he sounds like he's not acting horribly. Just tired.
I wouldn't put him down yet. I'd try to debride (exfoliate the dead skin off) the area until you can see a little blood coming up.

EDIT: But DEFINITELY treat him for mites like Cas said.

None of the black stuff is coming off

Is it bleeding? The black skin I mean.

Have you treated him for mites with permethrin dust or spray? If not, that's what I would do ASAP.

Do you think this is because of mites? Not saying they shouldn't treat, of course, just curious what your thoughts are.

I don't have any.

Can you go buy some?

@casportpony do you think it could be something like in this thread? It reminds me of it a bit, just without an actual WOUND.

I have not seen mites do that type of damage. Not saying it's not mites, just that I haven't seen it before.
