Is anyone familiar with essential oils and/or Melaleuca products? My poor Red (Buff Orpington roo) has frostbite on his comb. I have no bag balm, no Vaseline, no Neosporin. I DO have MelaGel, and essential oils. Is Tea Tree oil safe to use on chickens? What about essential oils, such as Lavender, or Frankincense? What other essential oils can I use on it?
