Using Rosemary in the Chicken Coop
Rosemary has anti-fungal and anti-bacterial properties. Plus it's great for repelling insects. In my coop, I like to hang it in bundles and make it into an insect spray. I mix some rosemary essential oil with water and spray it all over.
This year we had a swarm of bee-like flies that just wouldn't leave our coop. It was early spring and I had just gotten new plants. Once I hung my rosemary bundles and used fly spray, the flies were gone and haven't come back.
If you have space and/or live in a southern clime, you can plant rosemary near the coop to repel pests.
I also add rosemary to my chicken's nest boxes. Not only does it keep insects at bay, but it also calms my hens as they're laying.
