Question about Cocci and new chicks/ pullets

[CoopDeDoo]

Hello,

My current flock of older hens was diagnosed with a heavy load of Cocci yesterday ( via fecal sample ). They have been started on Corid. We will be putting our chicks ( who are on medicated feed) out in an adjoining run (separate coop)in a few weeks and also adding some pullets from a breeder friend ( I will check to see if they are on medicated feed or not).

So my questions are:
1. Do I need to add Corid to the water once the chicks are outside and stop the medicated feed or is the feed good enough?

2. If the pullets that I am adding are not on medicated feed - do i need to do any kind of preventative treatment for them?

Up until this point ( 4 years with chickens), I have never added outside chickens to my flock - only chicks that I have raised. My chicks have not been vaccinated for Cocci.

Thanks!

Lori

I immediately remembered this post when I read your question.

FDA recommendations:
http://www.accessdata.fda.gov/scripts/animaldrugsatfda/details.cfm?dn=013-149
"Chickens
Indications: For the treatment of coccidiosis.
Amount: Administer at the 0.012 percent level in drinking water as soon as coccidiosis is diagnosed and continue for 3 to 5 days (in severe outbreaks, give amprolium at the 0.024 percent level); continue with 0.006 percent amprolium-medicated water for an additional 1 to 2 weeks."

Doses listed are per US gallon.
The .006% dose for Corid Powder is 1/3 teaspoon (1.134 grams).
The .006% dose for Corid liquid is 1/2 teaspoon.

The moderate outbreak dose (.012%) for Corid Powder is 3/4 teaspoon (2.268 grams).
The moderate outbreak dose (.012%) for Corid liquid is 1 teaspoon.

The severe outbreak dose (.024%) for Corid Powder is 1.5 teaspoons (4.536 grams).
The severe outbreak dose (.024%) for Corid liquid is 2 teaspoon.

Dose for Amprol is the same.

I know it doesn't answer your questions, but it might help you come up with a plan.

If it were me and I had birds already being treated for an outbreak, chicks going on the ground soon as well as new birds coming in.....no I would not rely only on medicated feed but I would run the preventative dose of Corid (amprolium)

Thank you all for the advice and information! I will do a preventative treatment for the chicks/pullets with Corid when they go outside. Seems the most logical approach!

Thanks again!

**UPDATE**
Ok, we are officially at one week of treatment. 1 tsp per gallon of Corid. Of the three hens that were experiencing symptoms, none are really better ( or worse). I honestly believe I am looking at internal layers and that the Cocci is secondary. BUT... do you all think that I should treat for "severe" infestation at 2 tsp per gallon for a week?

Maybe this should be a new thread topic, but is there anything that can "mimic" internal laying? None of them have ever had any respiratory or neurological symptoms. We have never added any chickens to the flock other than feed store chicks - no adult or juveniles. We lost one of the GSLs to internal laying last year and these 3 ( 2 GSLs, 1 BR) are the same age and from the same group as the one we lost.

Thanks for any advice!

You could try the .024% for another five days and see if that helps. If they were mine, that's what I would do, but I'd also give them an additional oral dose at .2ml per 2.2 pounds of body weight. Have your older hens be de-wormed with Safeguard or Valbazen? If not, that's something you could try.

Should I look at de-worming even though their fecal sample showed no sign of worms? I have started the increased dose of Corid.

Thanks for all your help!
