9 Best Herbs for Chicken Immune System Health

These nine common herbs can help to support backyard chickens' immune systems and keep them healthy naturally.

Herbs of all kinds provide some pretty amazing health benefits for both people and poultry! 

But if you are specifically looking to add some herbs to your backyard chickens' diet to support their immune system and keep them as healthy as possible, you can't go wrong with these nine common herbs.

By incorporating some beneficial herbs that specifically target the immune system, you're providing your flock the tools they need to stay healthy. A strong immune system is the best defense against all kinds of illness that might otherwise befall your chickens. 

The immune system  (of people and poultry) is very complex - and extremely hard-working. It serves as a barrier to harmful invading substances and organisms, rids the body of toxins, and works in harmony with the circulatory, digestive, respiratory and even skeletal systems to keep a body healthy and working properly. 

As such, adding herbs to your flock's diet isn't a one-time thing, and not meant to treat a particular sickness, but instead herbs should become a natural addition to your chicken keeping routine and should be fed on a regular, on-going basis to work towards long-term optimal health.


9 Best Herbs for Chicken Immune System Health

My chickens have had their own herb garden right next to the coop for several years now. I plant all kinds of herbs each spring, along with the few that are perennials and come back each year, and let my flock forage to their hearts content in the garden when they get free range time.

You can also freeze or dry the fresh herbs to continue feeding them through the winter months.

I firmly believe that animals know what they need, when and how much and all you need to do is provide them the tools to keep themselves healthy. 

If you can't free range your chickens or don't want to plant them their own garden, you can just pick the fresh herbs and offer them to your chickens (and ducks). 

My chickens, and especially my ducks (all of these herbs are great for them too!)  love anything green. They'll nibble fresh herbs right out of my hand, but if your flock isn't quite as enamored with the idea, there are a few ways to incorporate these immune system healing herbs to them. 

You can offer all parts of the plant: flower heads, seeds, blossoms, leaves and stems to your flock.

Feeding Herbs for Chicken Immune System Health

Feeding Fresh Herbs

  • Offer herbs free-choice in a bowl, tossed on the ground or straight from the garden
  • If you have ducks, just toss the herbs into a tub of water and they'll be thrilled
  • Mix herbs into scrambled eggs or oatmeal
  • Tie herbs in a bundle and hang in the coop or run
  • Toss fresh herbs into their water tub (ducks especially love this method!)
  • Freeze fresh herbs into ice cubes or an ice block in the summer and put it in the water

Feeding Dried Herbs

  • Dry the herbs and mix them into scrambled eggs or oatmeal

Feeding Baby Chicks Herbs for Chicken Immune System Health

These herbs are all perfectly safe (and super beneficial!) for baby chicks and ducklings as well as for adult birds. 

By sprinkling some fresh or dried herbs on top of your baby's feed, they will get used to the taste and reap all the immunity benefits right from the start! Or brew some "herbal tea" for your littles (your older hens will love this too!) 

I also love to hang bundles of fresh herbs right in the brooder and let the chickens amuse themselves by nibbling on them.
