I recently had a very bad injury to one of our chicks ... The poor thing got stuck and the other chickens damn near ate it's butt off. Seriously, all the feathers were gone around its rump. and just a bony stump was protruding in a blood pecked at mess! His blood got onto other chicks and they got picked nk as well but not nearly as bad. 5 total assaulted. I rinsed with hydrogen peroxide and water to clean it. Then I applied a paste mixture of fresh ground usnea, coconut oil, Grapeseed oil, Tamanu oil, meadowfoam seed oil, lavender EO, niaouli EO and Manuka honey medical grade. (I already had the CO, TO, MFSO and GO blend made up so it was just easy to grab and use. I had just gotten the Manuka honey and wanted to try it out. Any honey is a great wound healer) Next time, hopefully there won't be, I think I'll just do the honey & usnea. The bleeding stopped almost immediately. I kept the chicken in isolation and rinsed the wound twice a day for three days with a herbal decoction of lavender, garlic, plantain, calendula and chick weed then reapplied the paste. The chicken healed very quickly with no sign of infection. When I returned him to the flock I painted the injury with blue food coloring to be sure that the other chickens didn't see it as something to peck at as they are attracted to red and are quite nosy little buggers
If you've no knowledge of usnea I HIGHLY recommend a google search. Chances are it's growing in your yard or nearby, unless your in the desert SW
it's been effective on treating cuts on my hands as well.
