Welcome to Modern Agriculture!
Chickens are some of the most charming and delightful creatures in the world of backyard animal husbandry. However, with the joys of keeping chickens come the challenges of keeping them healthy. One of the most common ailments that backyard chicken keepers encounter is coccidiosis. But don’t worry, there’s a treatment that can help: Corid.
Here is everything you need to know about Corid for chickens, including the recommended dosage and how to use it properly.
Here’s a snapshot of Corid:

The infection is caused by protozoan parasites of the genus Eimeria, which can cause severe damage to the intestinal lining of the bird, leading to diarrhea, dehydration, and even death in severe cases. The parasites can be found in soil, water, and the feces of infected birds.
Symptoms of coccidiosis can include droopy behavior, decreased appetite, bloody diarrhea, mucous in droppings, pale skin color, rapid decline in health, and huddling together. When chicks are infected with coccidiosis, they often go from bad to worse, making it crucial that they receive care as soon as possible. If you suspect that your birds are infected with coccidiosis, it’s important to take action quickly to prevent the spread of the infection and to help your birds recover.
If you notice that only a few chickens are displaying the symptoms of coccidiosis, separate them from the rest of the flock. Quarantining them ensures that you can give them the treatment they need without risking the health of the other chickens.
Corid is a brand name of Merial, an animal health company, that is used for a medication that contains the active ingredient amprolium. It’s used to treat coccidiosis in chickens and other livestock. Amprolium works by stopping the growth and reproduction of the protozoan parasites that cause coccidiosis.
Corid is available in both liquid and powder forms and can be found at most feed stores. Since coccidiosis does not have an age minimum, Corid is formulated for chicks as young as a couple days old. You will have to adjust the dosage accordingly. It’s important to use Corid as directed and to consult with a veterinarian or poultry expert before administering the medication.
The recommended dosage for Corid is 9.6cc (1.5 teaspoons) per gallon of water for the first five to seven days, followed by a maintenance dose of 4.8cc per gallon of water for an additional 14 to 21 days. The medication should be added to the bird’s drinking water, and it’s important to make sure that the birds are only drinking water that contains the medication.
If you are using the liquid form of Corid, you can measure out the appropriate amount and mix it directly into the chickens’ drinking water. If you are using the powder form of Corid, you will need to mix it with water according to the instructions on the package.
To help you decide approximately how much Corid to use per chick or chicken, here is a nifty chart:

You can attempt to give very lethargic chickens some medicated water through a dropper. Otherwise, provide the medicated water as the only source. Continue mixing water medicated with Corid for about 5-7 days at the highest recommended dosage.
Again, once you start seeing an improvement in your chickens after 5 days, you can begin to lower the amount of Corid to the suggested maintenance level. This will give you time to tackle the issue and clean up the area.
Furthermore, while your chickens are undergoing treatment, it’s important to monitor them closely for any signs of improvement or worsening of their condition. You should also keep an eye on their water intake to ensure that they are drinking enough of the medicated water. If you notice any significant changes in their condition or behavior, you should consult with a veterinarian or poultry expert.
Like any medication, Corid (amprolium) can have side effects. That is why it is important to follow dosage recommendations and guidelines.
Some chickens may experience minor digestive issues such as diarrhea, decreased appetite, and reduced egg production. In rare cases, more serious side effects such as anemia or a drop in egg production may occur. If you notice any unusual behavior or symptoms in your chickens while using Corid or any other medication, stop using the medication immediately and consult with a veterinarian or poultry expert. They will be able to provide you with advice about how to proceed.
Yes, it is possible to accidentally overdose your chickens on Corid. Overdosing can lead to side effects such as dehydration, reduced egg production, and digestive issues such as diarrhea.
If you accidentally overdo it with Corid, remove the medicated water from the area immediately. Swap in fresh water and an electrolyte supplement if your chickens have diarrhea. When necessary, call a veterinarian for further guidance.
It’s worth noting that overdosing on Corid is rare, and it’s usually only a concern if the medication is given at excessively high doses or for extended periods. As long as you follow the recommended dosage and treatment duration, your chickens should be able to tolerate Corid without any issues.
Preventing coccidiosis in chickens involves taking several measures to keep the environment and birds clean and healthy. Here are some ways to prevent coccidiosis in chickens:
Proper storage of Corid is essential to maintain its effectiveness and safety. Both the Corid liquid concentrate and powder should be stored in a cool, dry place, away from direct sunlight, heat sources, and moisture. Typically, the temperature should be between 59-86°F (15-30°C). Temperatures below 40°F (4°C) or above 104°F (40°C) should be avoided as they may affect the efficacy and stability of the medication.
If you purchased liquid Corid, store it in its original container with the lid tightly sealed to prevent evaporation or contamination. If the container is damaged, transfer the liquid concentrate to a clean, tightly sealed container.
For Corid powder, avoid using the same scoop or measuring cup for non-medicated feed. You want to limit cross contamination as much as possible.
Coccidiosis can be a serious health issue for backyard chickens, but with the help of Corid and proper management techniques, you can help your birds recover and prevent future outbreaks. As always, it’s important to consult with a veterinarian or poultry expert if you suspect that your birds are infected with coccidiosis or any other health issues. With a little bit of knowledge and preparation, you can keep your feathered friends happy, healthy, and thriving.
