Have you ever faced the heart-wrenching situation of watching your beloved chickens fall ill? Last spring, in my own backyard, I noticed my usually lively hens becoming lethargic.
One by one, they started showing signs of distress. It didn’t take long for me to realize they were battling coccidiosis, a disease that can swiftly devastate a flock.
The fear of losing them was overwhelming. But then, I found a beacon of hope: Corid.
Corid isn’t just a drug; it’s a lifesaver for chicken enthusiasts like us. But the key to its effectiveness lies in the correct dosage.
Have you ever wondered how much liquid Corid per gallon of water your chickens need? It’s crucial to get this right for both treatment and prevention.
As a preventive measure, I learned to use 1/3 teaspoon of 20% soluble Corid powder per gallon of water, and ½ teaspoon per gallon for the 9.6% solution. The dosage might vary, especially if coccidiosis has hit your flock hard.
I invite you to join me as we dive deeper into the world of Corid, understanding its nuances and how to use it effectively.

What Is Coccidiosis and Symptoms to Look for
As I was dealing with the coccidiosis outbreak in my flock, I realized how crucial it was to understand the disease itself.
Coccidiosis, I learned, is a parasitic disease caused by coccidia protozoa, affecting the intestinal tract of chickens. It’s not just common but can be severely detrimental to poultry health.
The symptoms were clear in my chickens. They started with diarrhea, some of it bloody, which was alarming. Then, I noticed their energy levels dropping; they were lethargic, moving less, and spending more time resting.
Their feathers lost their usual gloss, appearing ruffled and unkempt, and their appetite diminished significantly.
I understood that if left untreated, coccidiosis could lead to high mortality rates, especially in the younger birds of my flock.
How Does Corid Work, Side Effects, and When to Avoid it
As I administered Corid to my ailing chickens, I delved deeper into understanding how this medication works. The key ingredient, Amprolium, cleverly mimics thiamine (Vitamin B1).
This mimicry is crucial because it disrupts the life cycle of the coccidia parasites, preventing them from reproducing and spreading throughout my flock.
It was fascinating to learn how this drug outsmarts the parasite, giving my chickens a fighting chance to recover.
However, during the treatment, I remained vigilant for any side effects. Some of my chickens showed a temporary lack of appetite and mild diarrhea, which are common reactions to Corid.
I also learned that overdosing could lead to more serious issues, like neurological symptoms, so I meticulously followed the dosage instructions.
An important consideration I came across was when to avoid using Corid. If any chicken showed signs of an allergic reaction to Amprolium, or if they were suffering from conditions unrelated to coccidiosis, such as bacterial infections or worms, Corid wouldn’t be the right course of action. Fortunately, none of my chickens had such complications.
How Much Liquid Corid Per Gallon Of Water For Chickens Is Needed?
Corid 20% Soluble Powder
The next critical step in my journey to nurse my chickens back to health involved figuring out the precise dosage of Corid.
I had two options: liquid Corid and Corid 20% soluble powder. The challenge was to calculate the right amount per gallon of water for my chickens.
For the 20% Corid soluble powder, I followed a specific protocol. During the initial outbreak, the 5 Day Treatment plan was my go-to.
I mixed the Corid powder in water, ensuring to administer it at a dosage of 10 mg per kg of chicken weight for five consecutive days.
This precise measurement was crucial to ensure the effectiveness of the treatment without causing any harm due to overdosing.
Looking beyond the immediate treatment, I adopted a 21-Day Prevention Plan. This plan was designed to prevent future outbreaks of coccidiosis in my flock.
For this, I administered 5 mg of Amprolium per kg of chicken weight daily for a span of 21 days. This proactive approach was key to maintaining the long-term health and safety of my chickens.
Corid 9.6% Oral Solution
Having successfully used the Corid 20% soluble powder, I turned my attention to the Corid 9.6% Oral Solution, another formulation available for treating coccidiosis in chickens.
This liquid form required a different approach in terms of dosage and administration.
For the treatment protocol, I learned that 16 ounces of Corid should be mixed with 100 gallons of water. This ratio was critical to ensure that each chicken received an adequate amount of the medication through their drinking water.
In cases where a more direct approach was needed, such as with severely affected birds, I used the drench treatment method.
This involved mixing 3 ounces of Corid per pint of water, allowing me to administer the medication more directly.
As a preventive measure, I adopted a slightly different protocol. I used 8 ounces of Corid per 100 gallons of water, or 1.5 ounces per pint for the drench method.
This lower concentration was sufficient to keep the disease at bay without exposing my chickens to unnecessarily high levels of medication.
Understanding how these doses were calculated was vital. They adhere to FDA guidelines, which specify a concentration of 0.012% Amprolium for initial treatment post-diagnosis (lasting 3-5 days), 0.024% for severe outbreaks, and a maintenance dose of 0.006% as a follow-up.
These guidelines helped me ensure that I was using the right amount of Corid to effectively treat and prevent coccidiosis, keeping my flock healthy while adhering to recommended safety standards.
Starting Treatment and How to Administer Corid
Corid is available over the counter in several countries, making it easily accessible. This was a relief because it meant I could start treatment right away without any delay.
Corid isn’t an antibiotic but a coccidiostat, a type of medication specifically designed to control coccidiosis.
Regarding egg and meat safety, I learned there is no egg withdrawal period when using Corid, which was great news. However, a 3-day meat withdrawal period is recommended, ensuring that any residues of the medication are cleared from the birds’ systems before they are processed for meat.
Administering Corid turned out to be straightforward. The medication is mixed into the chickens’ drinking water.
The key was to calculate the correct amount of Corid based on their daily water consumption. It was important to ensure that the only water available to them during treatment was the medicated water.
This meant replacing their water supply with a freshly prepared medicated solution every 24 hours and discarding any unused solution from the previous day.
How Fast Does Corid Work and How Effective is it?
As I administered Corid to my chickens, one question lingered in my mind: how quickly would it work? The answer came sooner than I expected.
Within 24 hours of starting the treatment, I began to notice a positive change. The hens that had been lethargic started to perk up, showing more energy.
Even their appetites seemed to improve, a clear sign that the Corid was doing its job.
This rapid response was a huge relief. Seeing my chickens recovering so quickly reinforced the effectiveness of Corid in both treating and preventing coccidiosis.
It was amazing to witness how a treatment could turn things around in such a short time.
Can you Give too Much Corid to Chickens?
As the days passed and my chickens continued to show improvement, a new concern arose: the risk of overdosing them with Corid.
I had learned that while Corid is effective, Amprolium, its active ingredient, has a very small margin for error. Giving too much Corid could lead to serious consequences.
I was alarmed to discover that an overdose of Corid could cause severe spontaneous internal bleeding, serious neurological problems associated with immunosuppression, a reduction in egg production, and in the worst cases, death. This information heightened my sense of responsibility and caution in administering the medication.
With this knowledge, I became even more meticulous in measuring the correct dosage of Corid. It was crucial to strike a balance: enough to treat and prevent coccidiosis but not so much as to harm the chickens.
I double-checked my calculations and ensured that the concentration of Corid in their water was precisely as recommended.
Amprolium Resistance and Corid Alternatives
As my chickens recovered, I faced another potential challenge: the possibility of Amprolium resistance. Though rare, I learned that resistance to Amprolium, the active ingredient in Corid, could develop, which would necessitate exploring alternative treatments.
Coccidiosis is primarily caused by the coccidia genus Eimeria, which comprises various species. The effectiveness of Corid varied depending on the specific Eimeria species infecting the birds.
It was more effective against Eimeria tenella and E. acervulina but less so against others like E. maxima, E. mivati, E. necatrix, or E. brunetti.
This variability made me realize the importance of understanding the specific nature of the infection affecting my flock.
In addition to Eimeria, other coccidia such as Isospora sp. are usually susceptible to Amprolium, while Atoxoplasma is known to be resistant.
This knowledge was crucial in guiding my future prevention and treatment strategies.
Given the potential for resistance, I explored Corid alternatives. Other anticoccidial agents like toltrazuril, ponazuril, and sulfadimethoxine were options I considered.
Unlike Corid, which is based on Amprolium and available over the counter, some other drugs, like Sulmet, are antibiotics and require a veterinary prescription.
This difference is also why Amprolium is often found in medicated chick starters that are readily available.
Conclusion
As I reflected on my journey through the outbreak of coccidiosis in my flock, I was struck by the importance of knowledge, vigilance, and the careful use of medication like Corid.
This experience had been a profound learning curve, teaching me not just about the disease and its treatment, but also about the resilience of my chickens and the depth of my commitment to their well-being.
The key takeaway from this episode was the critical role of correct dosage in the use of Corid.
For the 20% Corid soluble powder, the treatment dosage was 10 mg per kg of chicken weight for five consecutive days, while the prevention dosage was 5 mg per kg daily for 21 days.
For the 9.6% Corid oral solution, the treatment protocol involved mixing 16 oz of Corid with 100 gallons of water, and for prevention, 8 oz of Corid per 100 gallons.
This careful measurement ensured the effectiveness of the treatment while safeguarding against the risks of overdose.
