How deep are the wounds? Please post pics. Is their behavior still normal? You should definitely keep them separated from other birds to keep them from pecking at their wounds. Stop the bleeding and disinfect the injuries with saline solution (not hydrogen peroxide) and you can use some Neosporin (no pain relief) too. If you don't have antibacterial ointment you can use bluekote instead if you have any, but I only like to use that if I have to. Check the rest of their bodies to make sure you haven't missed any wounds, because those feathers can often hide some smaller injuries that cause problems later on. Basically treat them like you would for any injury you'd get on yourself. You said one was limping. How are her legs? Are they swollen? Can she walk at all?
