I do not use essential oils, but what you are using is the same basic ingredients that are found in Vet RX which I haven’t used either. The difference is VetRX has pine oil, and it is in a corn oil base with a little alcohol. No amounts are given, so I would be careful mixing my own. It is an old remedy, I don’t know if it helps or not, but it seems that many use it. Here is a link with ingredients:

It can be common to have a respiratory disease brought in by wild migrating birds. Infectious bronchitis and mycoplasma (MG) are common in many backyard flocks. The main thing is to keep your flock fed a healthy balanced feed, and make sure they have good air circulation inside the coop, keeping dust, ammonia odors, or wet moldy conditions to a minimum. You sound like you are doing that.
For your sick hen, you may want to medicate her with the antibiotic Tylan 50 injectable, give it orally by removing the needle from the syringe. Dosage is 0.3 ml per pound twice a day 12 hours apart for 3-5 days. Tylan is a good treatment for MG. 1 day egg withdrawl after oral treatment. If she has IB, she may remain symptomatic for up to a minth, but it ususally involves frequent sneezing. Eggs may be wrinkle or soft with IB.
