*I am in no way a chicken expert. I have only been in the chicken business for just over a year. I have, however, been in the Essential Oil club for 3 years, and have done a LOT of research and learning on them. I wouldn't call myself an expert on those either, BUT I have a LOT of resources.

PLEASE, do not use an essential oil unless you KNOW it is of high quality. PLEASE PLEASE, do NOT use 'grocery store oils', as you never know what could be in them (even if they are labeled as "pure essential oils" or "all natural" ect.). I ONLY trust oils from one specific company. *
I add a drop of oregano oil to my chickens water every so often, along with a splash of apple cider vinegar. My big kids were a year old early in June, and they have never had any illnesses.
Lavender can help them chill out a bit, so when they have a situation where they might be stressing out, they get a drop of lavender. I have heard that eating lavender isn't good for them, however I've only put it in their water a few times and it didn't seem to hurt them. I only put 1 drop into a 2 gallon waterer.
Fennel is amazing for supporting female reproductive health, so my girls occasionally get a drop of fennel in their water. It helps support their egg laying department. Again, I usually use 1 drop in their whole waterer.
Yes, essential oils will float on top of the water, BUT their goodness does get incorporated into the water. For reference, I like to drop oils into my own water. I usually use my stainless steel cup with a reusable straw. I will have my water with the straw, and drop my oils on top. The oil floats on top, but when I take a drink with my straw, I can taste the oils!
I have also been meaning to do some extensive research, and come up with the perfect recipe for a multi-purpose "coop spray" that'll do it all. Help with pests, deodorize, and be beneficial to the girls. If ever I figure it out, I will definitely share
