Ooh, good to know. I used it since it was what I had on hand, and there was a study that said poultry dusted with this showed a decrease of mites. But that was mites not lice

figured it wouldn’t hurt...
Thank you for the heads up!
I looked it up and it seems that the general consensus is that it should be fine... I read a promising article on the effects of tea tree oil on louse in humans. I just made a 2% solution and sprayed her lightly with it, it helps that she puffs up, lol. for her crest and beard I worked it in with my fingers. fingers crossed that this will work for chicken lice also!
