How to Get Rid of Coccidiosis in Chickens Naturally?

I have raised chickens in my backyard for over eight years. One of the scariest moments I faced was when I saw blood in my young birds’ droppings. That is how I first learned about Coccidiosis.

I want to share what I have learned about treating this sickness without using harsh chemicals. After trying many things, I found ways that really work. This guide will help you spot the problem, fix it with natural items from your kitchen, and keep your flock safe. I will use very simple words so anyone can understand.

What Is Coccidiosis? (Explained Like You Are 10)

Coccidiosis is a sickness that hurts a chicken’s gut. It is caused by a tiny bug called Eimeria (say “eye-MEER-ee-ah”) that lives inside the chicken’s poop. This bug is a parasite. A parasite is a living thing that eats and lives on another living thing and makes it sick.

This bug can not be seen with your eyes. It is a one‑celled animal. Once it gets inside a chicken, it starts eating the chicken’s insides. That makes the chicken very sick.

Here is the important part. Almost every chicken has a tiny bit of this bug in its body. But when a chicken gets too stressed, or when the coop is very dirty, the bugs grow too fast. Then the chicken gets sick.

The bug is spread through poop. One sick chicken poops. Another chicken pecks at the ground. The second chicken eats the bug. Now the second chicken is sick too.

Who gets this sickness the most? Young chickens (chicks) under 12 weeks old get very sick fast. Adult chickens can also get it, but their bodies are stronger.

How to Know If Your Chicken Is Sick (Watch for These Signs)

You need to watch your chickens every day. The faster you see the signs, the faster you can help them. Here are the things I look for:

Sign of Sickness	What It Looks Like
Bloody Poop	You see red blood in the droppings. This is the biggest sign.
Sitting Puffed Up	The chicken sits alone. Its feathers look puffed and messy.
No Eating	The chicken does not run to the food anymore. It just stays still.
Pale Comb	The red skin on top of its head (the comb) turns pale pink or white.
Runny Poop	The poop is very wet. Sometimes it is full of mucus (looks like snot).
Chicken Is Thin	You feel the breastbone sticking out. The chicken has lost weight.

😟 Personal Experience: The first time I saw bloody poop, I almost panicked. I thought a predator had hurt my chicken. But then I noticed the chicken was just sitting alone. I called a friend who knows chickens, and she said, “That is coccidiosis.” That is how I started learning about natural ways to fix it.

The 7‑Day Life Cycle of This Parasite (Understand to Beat It)

This bug has a life cycle. It takes about 4 to 7 days from start to finish. Here is what happens:

A sick chicken poops. The poop has tiny bug eggs called “oocysts” (say “OH‑oh‑sists”).
The eggs sit in the litter. They need a few days in warm, wet litter to become dangerous.
A healthy chicken pecks the ground. It swallows the eggs.
The eggs hatch inside the chicken’s gut. The baby bugs eat the inside of the gut.
The baby bugs make more eggs. Those eggs come out in the poop.

This is why cleaning the coop every single day is so important. If you break the cycle, the bugs can not spread.

My 7 Natural Ways to Treat Coccidiosis

Remember: Natural remedies work best when you catch the problem early. If your chicken is very weak and not eating at all, you need to see a vet. Natural is not magic. But for mild to medium sickness, these steps helped me save many chickens.

1. Apple Cider Vinegar (My Favorite Tool)

I put apple cider vinegar (ACV) in my chickens’ water every week. It makes the inside of their gut a bad place for the coccidia bug to live. This bug does not like sour things.

Here is my simple recipe:

Chicken Age	How Much ACV	How Much Water
Baby chicks (under 8 weeks)	1 teaspoon	1 gallon of water
Adult chickens	2 tablespoons	1 gallon of water

Give this mix for 3 days in a row. Then stop. Repeat the next week if they are still sick.

✅ Important Tip: Always use glass or plastic waterers. ACV will eat through metal waterers. I learned this the hard way when my metal waterer started leaking rust.

You need to buy ACV that says “with the mother” on the label. That means it has good bacteria that help your chickens.

2. Oregano Oil (Very Strong Bug Fighter)

Oregano oil is like a superhero against bad bugs. Studies show that it fights coccidia very well. It is very strong, so do not use too much.

Here is my simple recipe:

Add 1 drop of oregano oil for each gallon of water.
Give this for 5 to 7 days.

You can also chop fresh oregano leaves and mix them with their food. I grow oregano in my garden just for my chickens.

⚠️ Be careful: Oregano oil is very strong. Do not give more than 2 drops per gallon. Too much can burn their mouth.

3. Garlic (Simple and Cheap)

Garlic is another bug fighter. Studies show that garlic mixed with turmeric and ginger works well against coccidia. Here is what I do:

Take 1 fresh garlic clove for every 2 chickens.
Crush the garlic. Crushing makes the good stuff come out.
Mix the crushed garlic into 1 gallon of water.
Let it sit overnight. Then give it to your chickens the next day.

You can also chop garlic very small and sprinkle it on their food. My chickens love garlic.

4. Turmeric (Heals the Gut)

Turmeric is a yellow spice. It helps heal the chicken’s insides after the coccidia bugs have hurt them. Studies show it lowers the damage coccidia causes.

Here is what I do:

Mix 1 teaspoon of turmeric powder into each pound of feed.
Use it for 1 week straight.

Turmeric also helps the chicken’s own body fight back against the bugs.

5. Probiotics (Good Bugs Fight Bad Bugs)

Probiotics are good bacteria. They live in a chicken’s gut and help it stay healthy. When a chicken has coccidiosis, the bad bugs have killed many good bugs. You need to add the good bugs back.

Here is how I add probiotics:

What to Use	How Much	How Often
Plain yogurt (no sugar)	1 tablespoon per chicken	Once a day for 5 days
Probiotic powder (for poultry)	Follow the bag instructions	Once a day for 7 days

Research shows that probiotics help chickens fight coccidia by making the gut stronger.

6. Coconut Oil (Protective Layer)

Coconut oil has a special fat that some people think makes it harder for coccidia to stick to the chicken’s insides. I am not 100% sure, but I use it anyway because it helps keep my chickens healthy in other ways.

Melt 1 tablespoon of coconut oil.
Mix it into their feed.
Give it every other day for 1 week.

7. Change Their Food (Make It Easier to Digest)

When a chicken is sick, eating normal hard food is hard for its gut. I switch to soft, easy food. Here is my sick‑chicken recipe:

Take their normal feed and add warm water. Make it like oatmeal.
Add 1 teaspoon of apple cider vinegar.
Add a pinch of turmeric.
Let it cool down, then give it to them.

Soft food is easier to eat and easier to digest.

My Personal Treatment Plan (What I Actually Do)

Here is exactly what I do when I see bloody poop in my coop:

Day 1:

I remove all the old water and give fresh water with 1 drop oregano oil and 1 tablespoon ACV per gallon.
I crush 2 garlic cloves per gallon of water and add that too.
I clean the entire coop. I remove all wet litter. I put fresh, dry litter.
I check each chicken. If a chicken looks very weak, I bring it inside my house into a warm, quiet box.

Days 2 to 5:

I give fresh oregano‑ACV water every morning.
I give soft food (wet feed with turmeric) twice a day.
I add 1 tablespoon of plain yogurt on top of their food once a day.
I keep the coop as clean as I can. I pick up poop twice a day.

Day 6 and 7:

I stop the oregano oil. The oregano oil is very strong, so 5 days is enough.
I keep giving ACV in their water for 2 more days.
I slowly go back to their normal food.

By Day 7, my chickens usually look much better. They run to the food again. Their poop is normal.

How to Stop Coccidiosis Before It Starts (Prevention)

Stopping this sickness is much easier than treating it. Here are the rules I follow on my farm.

1. Keep the Coop Dry

The coccidia bug loves wet, warm places. If you keep everything dry, the bug can not grow.

Do not let water spill inside the coop. Put waterers outside.
Add fresh dry litter every week. I use pine shavings.
Clean wet spots right away. If a waterer spills, I get a shovel and remove the wet bedding immediately.

2. Use the Deep Litter Method

This method sounds weird, but it works. Instead of cleaning everything every day, you add more dry litter on top of the old litter. You build it up.

Studies from Ohio State University found that deep litter helps chickens build immunity against coccidiosis.

Here is how I do it:

Step	What to Do
Start with 4 to 6 inches of dry pine shavings	Make it thick from the beginning
Every week	Add 1 more inch of fresh shavings on top
Every month	Stir the litter so it stays fluffy
Every 6 months	Remove half the old litter and start fresh

The deep litter has good bacteria that eat the coccidia eggs. It also makes the chickens stronger because they get tiny amounts of the bug over time, which builds their immunity.

3. Do Not Crowd Too Many Chickens

Crowding makes everything worse. When chickens are packed tight, the poop is everywhere. The bugs spread very fast.

Here is my rule:

Inside the coop: 2 to 3 square feet per chicken.
Outside run: 8 to 10 square feet per chicken.

If you have more chickens, you need more space.

4. Give ACV in Water Once a Week

I give ACV water to my chickens one day every week even when they are not sick. It keeps their gut healthy and strong. I use 1 tablespoon per gallon of water, just for one day a week.

5. Feed Herbs in Their Food

I mix dried herbs into my chickens’ feed once a week. Here is my mix:

Herb	How Much per Pound of Feed
Dried oregano	1 teaspoon
Dried thyme	½ teaspoon
Turmeric powder	1 teaspoon
Crushed garlic flakes	½ teaspoon

Herbs like oregano and thyme have been studied and shown to help prevent coccidia naturally.

Quick Reference Table: Natural Remedies at a Glance

Natural Remedy	How to Give It	Dosage	How Many Days
Apple Cider Vinegar	In water	1‑2 TBSP per gallon	3‑5 days
Oregano Oil	In water	1 drop per gallon	5‑7 days
Fresh Garlic	In water or feed	1 clove per 2 chickens	5 days
Turmeric	In feed	1 tsp per pound of feed	7 days
Probiotics (yogurt)	On feed	1 TBSP per chicken	5 days
Coconut Oil	In feed	1 TBSP for 6 chickens	Every other day

When to Call a Vet (Do Not Wait Too Long)

Natural remedies are great, but they are not always enough. Here is when I call my vet:

The chicken stops drinking water. A chicken that will not drink is a big problem. They can die very fast.
The chicken can not stand up. It falls over or sleeps all day.
There is a lot of blood in the poop. A little pink is bad. Full red blood is worse.
Natural remedies did not work after 3 days. If my chicken is not getting better by Day 3, I call a vet.
The whole flock is sick at once. If 4 or 5 chickens all look sick at the same time, you need medicine fast.

Vets use a medicine called Corid. It is a liquid that you put in their water. It usually works in 2‑3 days.

🙏 Personal Experience: One time I tried to treat a very sick chicken with only natural remedies. I waited too long. By Day 4, the chicken could not stand. I rushed to the vet, but it was too late. That chicken died. Now I do not wait more than 3 days. If my chicken is not eating or drinking, I go straight to the vet.

Final Thoughts from My Years Raising Chickens

Coccidiosis is a scary word, but it does not have to be a disaster. I have saved many chickens using the simple things I talked about here. Apple cider vinegar and oregano oil are my two best friends. Clean, dry litter is my third best friend.

The most important thing I have learned is to watch your chickens every single day. The faster you see the problem, the faster you can fix it. Do not wait. Do not hope it goes away on its own.

And remember: natural does not mean you never see a vet. Vet medicine saves lives. Use natural for prevention. Use natural for mild sickness. But when your chicken is very sick, get help.

You can do this. Your chickens trust you. And now you know how to help them.
