I saw a few very small white insects underneath my Rooster's feathers and after some research became convinced that it was lice. My very first time seeing them on my flock so i don't have any experience. I did some research and found some home remedies to treat my flock. Garlic juice and essential oils such as lavender, cinnamon etc infused with water to be sprayed on the chickens twice weekly . Has anyone used it before? Can i use tea tree oil in this recipe? Any other effective method to treat it naturally?
