Corid as a Preventative

[Fred's Hens]

Fred's Hens, the moderator had said recently that he gave it continuously in a weak dose for several weeks when they got on dirt after he had an outbreak for the first time. Michael Apple recommends using it 5 days every 3 weeks until 7 months I believe. I don't think amprollium really blocks thiamine, but it mimics thiamine in the coccidia oocyst or organism. Here is what is on the website:

How CORID works
Structurally, CORID mimics thiamin (Vitamin B1) which is required by coccidia for normal growth and reproduction. When coccidia ingest CORID, they experience thiamin deficiency and starve from malnutrition. CORID has been experimentally administered at many times the recommended dosage and duration with no signs of toxicity.

I agree. The protozoa apparently is "starved" of thiamine by the amprollium, as I understand it, by taking in the substitute. This is as much as I know, and it isn't much.

Folks often feed medicated (amprollium laced) feed all 18 weeks of a chick's life. Since we feed unmedicated feed, supplementing with "medicated water" so to speak, is our precaution. To date, it has worked well.

I've recently cut back to the 1/4 teaspoon "recipe" and used it for a shorter window of time with good results.

All that said, I am not prepared to get caught off-guard, as I foolishly was during an unexpected, virulent outbreak a year or so ago. One lives and learns. Hopefully.

How long do you do the preventative dose of corid? I have two weekers that haven't been outside yet. Planning to do this soon. Thank you!

Five to seven days. It can be repeated after three weeks, but it is good to supplement with vitamins and probiotics in the water for several days after each round of Corid. Chickens need to be exposed to small amounts of coccidia to help build up immunity to it, which sources say takes place between 11-20 weeks of age. Since there are more than 9 strains, new strains may be brought in by new chickens, or by moving chickens to new soil.

Perfect! Thank you! I am new to the backyard chicks and I have 4 two week old chicks. Can't wait to get them outside to play! Any other tips for a newbie?

Hello there again! My first batch of chicks have done great! However, I just got 8 new babies that are about two wks old. I moved them to a larger brooder and put pine shaving in two days ago. I had been using coop clean in the smaller. Today there is a lot of bright red and dark red blood in their stool. I started corrid but they are all acting totally normal. Happy and running around. Could they be eating the pine shaving? Should I go back to coop clean?? Thank you!!

I know this is an old thread but I'm hoping I can get some help. I just put my 12 chicks,3-4 weeks old, outside on the ground today. They are on medicated feed, but should I use corid in their water as a preventative as well? I live in a hot, wet climate so I want to play it safe. Any suggestions are welcome!

Old post, I know, but I'm interested in finding out what happened. It's like reading a book with the ending torn off. What happened? Hope all went well.
