Corid 20% powder and Amprol 128 20% powder are the same thing, both are 20% amprolium powder.

The powder doses for poultry are as follows:
  • The severe outbreak dose (.024%) for Corid Powder is 1.5 teaspoons
  • The moderate outbreak dose (.012%) for Corid Powder is 3/4 teaspoon.
  • The preventative dose (.006%) for Corid Powder is 1/3 teaspoon.






Based off of the above, 8 ounces is 226.8 grams.
226.8 divided by 50 gallons = 4.536 grams per gallon

I have one (5) pound hen to treat. Though I appreciate all the math, these conversions are difficult for me to follow and I'm left with the same hesitant question I had from reading the package, which is:
Per what?
1.5 teaspoon of powder needs to be consumed by her per day?
1.5 teaspoon of powder per a gallon, of which she may only drink a tablespoon per day?

I'm reading the drench for five days instructions on the package and your instructions. Will you verify that I've understood correctly?

I'll mix one ounce of powder to 1 1/4 cups of water. (Reducing since I'm only treating one bird.)
I'll give 1.5 cc of this mix each day for 5 days.


Please advise if I've calculated correctly. I have a 3 cc syringe. It appears cc and ml are basically interchangeable.

Thanks in advance!

(This is to treat my hen, who again isn't doing well, and who has tested slightly positive for Cocci - two were seen in the fecal sample.)
 
Your 5 pound hen needs 45mg of amprolium per day. Take 10 ml of water and place that in a container. Mark that container so you know where the 10 ml mark is. Empty... Now place 1/2 teaspoon powder and slowly add water until you reach the 10ml mark. Stir well. You now have 10ml of liquid with 27mg per one ml. Total daily dose for your five pound hen is 1.7ml of that liquid per day, but it will probably work better if you give it 2-4 times a day, so figure out how many times per day and divide 1.7 by that number. She should also have lots of fluids, so if you can, give that dose with with as much waters possible. Make sense?

Is the above dosing per gallon? Or per 5 gallons? @casportpony

Treat the whole flock. Then You won’t have to worry about specifically dosing each bird. Cocci is fast spreading so chances are more than just your one bird has it. Even if there are a few birds unaffected, the Corid powder will not hurt them. But just out out the one gallon of water as their only water source, use the dosing provided in previous post. Repeat for 5 days.
 
Wow, this is an old thread!

I clicked on the link and it came up with an error message. I have the powder. How do I make a drench?
I noticed abnormal droppings last week and took a sample to a local vet. He said all looked normal. (8 week old chicks of all different breeds) Today I went to my avian vet and he said the sample was loaded with coccidia. Really upset, I could have started treatment last week! Now I have to get on a plane tomorrow morning and be gone for 5 days. I’m super anxious leaving like this. Should I give a drench dose tonight before I leave? I prepared several 3 gallon waterers with the 1.5 teaspoons per gallon dose. Having a relative take the dog out while I’m gone but she won’t go near the chickens. I’m trying to be comforted by the fact that all are eating, drinking, and acting normal and lively. Do you think it’s okay that the medicated water won’t be replaced until I get back (5days). I’ve read to change it daily, but that’s not an option in my situation. Oh and they’re on medicated feed as of last week.
