If your not sure about the cayenne pepper treatment, try it on yourself the next time you have a wound. You are going to be tremendously surprised at how well and quickly it works to stop bleeding, kill pain and heal the wound.
I have to agree with this. I have used cayenne on myself, on dogs and on birds. I have not found it to really sting (and I am a total pathetic wuss when it comes to pain), and never have I seen a pain reaction in the dogs or birds I have used it on either.
Another alternative treatment that I use often for wound healing is honey - it has amazing healing properties on wounds. I have healed huge wounds very quickly and with minimal to no scarring with honey. (Several times these were wounds that really should have been stitched) It is messy and sticky and not always easy to apply, for for where your bird's wound is, a little honey could easily be applied with a q-tip. And I can guarantee it won't sting even for a second. I use it on myself all the time under a bandaid.
Actually today I used both cayenne and honey on me, when I cut myself at work (I am a dog groomer, and I snipped myself with the tip of my scissors). I dabbed on some cayenne to stop the bleeding, then dabbed on some honey and covered it with a bandaid to keep the dog hair out as well as to keep me from getting the freshly bathed blonde dog stained with my blood and cayenne hahaha
If you really want a more conventional treatment, Vetericyn has also worked well for me. It is totally non-stinging, and is safe even in the eyes. I used it recently on a dog with a large abdominal incision that had a staph infection starting around the area and I saw a measurable increase in healing within just a few hours after starting to use it. Many of my clients have had good success using Vetericyn on wounds, hot spots, rashes and ear infections.
