7 Natural Ways to Boost Your Chicken’s Immune System


Chickens Immune System


We often talk about having a good immune system, but what is it, and how does it work?

Learn More

The immune system is not well understood, even in humans; basically, it is the mechanism that fights off illness, disease, and infection.



That is a huge job since micro-organisms are constantly all around our chickens and us!

Many of these organisms are harmless, but some are pathogenic (disease-causing), and these are the ones our immune system fights.

For a chicken to effectively fight these organisms, the immune system must be in great shape and have everything it needs to be effective.

Those things are vitamins, minerals, good nutrition, low stressors, and sufficient rest.


There is no quick-fix or a single item that will fix everything – be skeptical of such claims. Your flock needs many things to aid the immune system.

Many other things govern the immune response also – genetic factors, age, gut health, inflammatory conditions, or poor environment.

We cannot change some of those things, but we can certainly help with good, beneficial food and supplements.

This time of year is a great time to check each hen for any health problems and treat them accordingly.

Ensuring your girls have a low-stress environment is important, so try to keep things mellow and routine around the coop. Chickens love routine.


Anything new can be stressful for them – unless it’s edible!

Rest, too, is essential. At this time of year, it may seem like all they do is eat or sleep, but that’s ok.

They have a busy year ahead of them. Once the egg-laying and chick-rearing season startup, those hens will have plenty to do, and it will take its’ toll on their bodies.

Chicken’s Immune System Booster 1: Garlic

Garlic is a powerful aid to the immune system. It is also antimicrobial, repels parasites, and is said to deter intestinal worms while stimulating the immune system.

You can add 4 cloves of crushed garlic to a gallon of drinking water. If your birds aren’t used to garlic, make sure they are drinking enough water – add another drinker of ordinary water if needed.

Do not use garlic in a metal drinker – garlic will corrode it.

You should change out the cloves every 2-3 days and replace them with fresh cloves.


You can also use fresh garlic powder if you have it on hand. As with most things, too much can be a bad thing – garlic can cause Heinz anemia which causes weakness in chickens.


Chicken’s Immune System Booster 2: Herbs

Many herbs are recommended to aid in chickens’ health and digestion. In fact, some commercial chicken concerns have started adding oregano and cinnamon oil to their birds’ diet.


Oregano – is the clear favorite for a healthful boost. It boosts the immune system and helps guard against certain infections such as salmonella, infectious bronchitis, avian influenza, and E. coli.

Cinnamon – is a great all-rounder. It has antibacterial properties, reduces inflammation, and is an antioxidant.

Turmeric – has great antibiotic and anti-infective benefits.

Ginger – is another anti-infective, anti-viral herb that boosts the immune system.

Parsley – rich in vitamins A, B, C, E, and K plus numerous trace elements, it is said to stimulate egg-laying.

The list can be extensive, but the herbs above are the most popular.

Although chickens don’t have a great sense of smell, they do possess one.

So sprinkling fresh herbs such as lavender in the coop and especially the nest boxes might put them in a calm and happy frame of mind.



Chicken’s Immune System Booster 3: Fruit

Frozen Fruit For ChickensMany fruits are healthy for your chicken: melons, watermelons, grapes, bananas, and berries being the most frequently offered.

Citrus fruit is one of those items that the jury hasn’t decided on. Many folks say their flock loves citrus (not lemons), yet others will tell you it’s bad for them but no details on what happens if they eat it.


Here are some of the fruits you can feed your chickens to boost their immune system:


Bananas – contain vitamins B6 and B12, plus magnesium, potassium, fiber, and protein. If like me, you don’t like eating bruised bananas, the girls will help you out!

Blueberries – Berries, too, are packed full of healthful nutrients. Vitamins and trace elements such as selenium and phosphorus abound. They aid in digestion and contain antioxidants. I love to watch the girls race after frozen blueberries…it gives them to exercise too.

Strawberries – another superfood for your ladies. Full of vitamins, minerals, antioxidants, and a powerful immune booster, plus the girls truly love them!

Raspberries, blackberries – the hens enjoy all. If you have a bramble patch, you will find a few intrepid hens in there eating all the berries they can find.



Chicken’s Immune System Booster 4: Greens

Fresh green veggies pack loads of vitamins and goodness. As an example – kale contains vitamins A, C, K, B6 plus calcium, potassium, copper, and manganese.

Your hens will enjoy some fresh greens as a treat, and it doesn’t have to be the ‘regular’ expensive supermarket greens; think dandelions, chickweed, and plantain.

Turn the ladies out to free-range, and they will head straight for the grass and peck away contentedly.

Dandelions – contain vitamins A, B, C, E, and K and numerous trace elements such as calcium and manganese. It is said to aid digestion; it is an antioxidant and an anti-inflammatory pain reliever, not too bad for a common weed!

Plantain – another firm favorite with healthful benefits. It contains vitamins and minerals, and the seeds are said to be a natural wormer and detoxifier.

You can also make a healing salve from plantain – there are several recipes on the web.


Other common weeds that are beneficial to your ladies are clover, chickweed, and wild strawberries.

Of course, this is just a small sampling of the goodness available for free, right under their beaks!

Chicken’s Immune System Booster 5: Tonics

The easiest and cheapest ‘tonic’ for your chickens is apple cider vinegar.

It is great for digestion and increases calcium absorption especially in the summer months – it is also mildly antiseptic. The recommended dose is 1 tablespoon/1 gallon water. Do not use metal containers.

It will cause them to corrode as it is acidic.

There are also numerous commercial ‘tonics’ and supplements out there too that are beneficial to your flock.


Chicken’s Immune System Booster 6: Seeds and Grains

Fermented feed for your ladies is an excellent way to boost their nutrition in the gloomy winter months.


Feed that has been fermented is higher in vitamins B, C, and K contains probiotics that help digestion, and increases the availability of the nutrients locked inside the grain.

This method of feeding decreases feeds consumption and waste, all while boosting the immune system!

Another quick and healthful idea for your birds is sprouted seeds. Seeds are very cleverly made. They keep many of the nutrients locked inside, and when eaten, do not give them up.

To unlock the seeds’ inner goodness, you can soak them in water until they start to sprout – they are then ready for the girls to eat.


If you take that one step further and let the seeds grow, you have fodder for your girls.

Cracked corn is a sure-fire crowd pleaser!

Give this to the girls in the evening before bedtime; otherwise, they will fill up on this instead of the more nutritious feed. This will keep their digestive tract busy through the night hours.


Chicken’s Immune System Booster 7: Eggs & Dairy

Eggs! They are good for you, and they are good for the chickens too! As a treat on cold days, mix some scrambled eggs – you can also add your dried herbs to the mix.


Chickens do not process milk products well, but you can give small amounts of yogurt to them.

My favorite mash is warm oatmeal with added birdseed, oregano, and 2-3 large dollops of yogurt. Mix it all and stand well back before they start flinging oatmeal everywhere

Don’t forget to give them the eggshells too. Bake the shells in the oven on low heat for about an hour and make sure the shells are crushed down into teeny, tiny pieces, so they aren’t recognizable as eggshells – you don’t want them eating their own fresh eggs!

Giving them back the eggshells helps them get more calcium into their bodies.
