I'll leave the flock management suggestions to others.
I do agree, it looks like they have been fighting.
Combs bleed, become a bit crusty from pecking. Some of the tips look like they may have a little frostbite damage as well, the points may fall off no big deal on that.
The only thing I see that I would keep watch on if it were my rooster is the eye (pictured below) He will probably heal fine as is, but if you notice discharge or pus flush with saline and apply an ophthalmic ointment like Terramycin or Vetericyn eye gel. Some of the scabs may take time to heal, depends on the flock, some roosters allow the girls to pick at scabs so they just reopen them.
