No shortage of articles circulate online about using mint with backyard chickens, but how much faith should you place in those claims when the health of your pet chickens is at stake? Let’s take a critical look at the most common claims made about mint to see what they look like when held up to the light.


The Claim is…that mint has a cooling effect on chickens in hot weather.
The Truth is…mint does not have a cooling effect on chickens in hot weather.
While we think of mint as refreshing in hot weather due to its flavor and mouth-feel, mint does not have magical cooling properties, nor a cooling effect on a chicken’s body temperature. Chickens probably don’t even perceive the minty “cool” flavor due to their extremely limited taste buds. Compared to a human’s nearly 10,000 taste buds, chickens have a mere 250! My chickens tend to leave mint and other herbs alone in my chicken yard and while there’s certainly no harm in growing mint in the chicken yard, mint does not lower a chicken’s body temperature.  Help chickens beat the heat with proven methods in this article.

The Effects of Mint on Chickens, Flies and Rodents in the Chicken Yard


The Claim is…mint repels insects from the chicken coop or yard.
The Truth is…mint does not repel insects.
While planting herbs around the coop makes for lovely landscaping that chickens are not likely to eat, herbs such as mint, lavender, and rosemary do not repel flies, mites or lice simply by growing near a chicken coop. If a mint garden could repel flies, every horse barn, commercial poultry house, and livestock yard in the world would have herbs growing around it! You won’t find fields of peppermint surrounding dairy farms or horse barns because fresh and dried herbs are not effective insect repellents.


The Claim is…mint deters rodents from the chicken yard.
The Truth is…mint does not deter rodents.
While some essential oils such as balsam fir or peppermint, in very high concentrations might repel some rodents if the strong scent sufficiently interferes with their ability to smell danger,very determined rodent will not be deterred by mint oils. However, it is unsafe to use essential oils around chickens at all because ingestion can be toxic, if not fatal. Mint planted around or placed inside the chicken coop does not discourage rodents because the scent is not strong enough to offend or alarm them.

Herbalist Susan Burek performed an experiment on the effect of mint on rodents in her chicken coop by placing mint around a known mouse nest;  the results were fascinating. See the YouTube video where the mother mouse lined the nest for her babies with the fresh mint leaves


The Claim is…mint added to chicken feed daily supports a chicken’s immune system.
The Truth is…mint added to chicken feed daily can be detrimental to hen health.
Poultry herbalist Susan Burek says, “I do not give herbs to my chickens every day. The misuse of herbs can cause those herbs to act indiscriminately and destructively, much like antibiotics. If you believe any herb has medicinal properties, you know that more often than not, the benefits relate to the effects of essential oils, not fresh or dried herbs. A credible herbalist will not recommend the use of any herb daily or indefinitely in a medicinal capacity. Medicine is not offered to healthy chickens. The daily use of herbs is limited to rebuilding core health of sick chickens and is discontinued either when core health is restored, when an infrequent maintenance level is indicated, or when the herb fails to work for the intended purpose, signaling the need to explore at a different health regimen.”
