Welcome To BYC
Do you have another rooster? Looks like he's been in a tussle.
Gather him up and rinse off the blood, you can use saline if you wish.
If he's got dried blood in his beak, give it a wipe out with a soft cloth or qtips.
Vaseline or triple antibiotic ointment on the comb, wattles and facial tissue, should help the skin heal up and he'll feel a little better.
Where is he kept? Photos of housing/run, etc. how many hens?
Foot might be a bit scuffed, hard to see them. You can rinse them off. Dry well, then apply a thin layer of vaseline to give added protection. Keep an eye on them. The red streaks down the legs are due to hormones.
