I read somewhere if you heat a potato, then stick it on the spur before you use the pliers, that will help control bleeding.You could also de-spur your roos. I've met people who've had roosters with such pointy spurs they can stab a hen so deeply that she didn't make it.
It's very simple to remove rooster spurs. The roosters even look prouder.
All you need is a pair of pliers, quick stop and gauze pads (if it bleeds at all).
Take the pliers and grip the spur firmly at the base (not tightly). And rock the pliers and the spur back and forth. There should be a pop or click and the spur will come off. There will be a raw new small spur with a little blood on it. Usually the spur won't bleed, if there are a few drops just take some quick stop and gauze and pat it on the new spur.
If you don't want to do that you can just clip the ends off with a pair of dog toe-nail trimmers.
Now talking about the hens.
Clean the wounds. (If you think they go to the muscle, get a vet.)
Put some antiseptic ointment (or Neosporin) on the cut.
You can get a blood disguise called "Blu-Kote". Dab it on next, so the other hens won't pick at the wound. Watch the wound every day to make sure it is doing alright.
Good luck.
For the hens wounds, I would flush with Betadine Solution.
