“Can you overdose chickens on corid?”

If your dosage is not extremely high, you won’t need to worry about corid overdose. The optimal dosage of corid is around 2 teaspoons per gallon of water. Or you can use 10 ml per gallon. The toxic level of corid is pretty high for chickens. However, there may be some side effects.

If you are concerned with corid, it’s better to know more about it. So, let’s dig deep into some facts and the treatment process of this medication.

Some Basic Things About Amprolium

Do you know what the interesting thing is? Although people may use corid frequently, Amprolium is the actual medical term. But that’s not all. There is still a lot more to clarify before I answer your question.

Amprolium is commonly used in the USA as Amprovine, Anticoccid, Corid, and so on. They are from different brands which serve the same purpose of solving coccidiosis. Apart from that, the medication is available in both powder and liquid form.

Now, you might be wondering if there are any side effects of this medicine? To answer your question, you need to understand corid first. Corid is actually a mimicking supplement for Thiamine (Vitamin B1).
