Corid Overdose! And it doesn’t seem to be working...

[Here_Chickie_Chickie]

I just got some new chickens! Yay!
Four of my 7or 8 wk old pullets out of a 14 bird flock have coccidiosis. Not yay!
One light Brahma, one sapphire gem, one speckled Sussex and one buff Orpington.
They are puffed up, bloody stools, not very active or alert, standing still, droopy wings, sleeping while everyone else forages. They are eating and drinking but just look sick.
I treated all the birds for coccidiosis. (And sent them breeder a text about treating her birds)

And then, in not the most shining moment of my chicken keeping career, I massively overdosed my birds on Corid 9.6%. Aparently I don’t know how to use a conversion calculator, and ended up giving them 12oz per 2 quart of water! (I know... I know...)
....and you would think the cocci would be Nuked after 1.5 days of that, right?
Well, the birds are all about the same. The well birds seem just fine and the sick ones are no different. It seems like the bloody poops may be less, but I am super worried now.
I know it says 24 to 48 hours for them to get better, but it’s past that.
worms maybe?

I would keep them on Corid (at a proper dosage level, haha, which is two teaspoons per gallon of water) because it takes awhile to kill them off and the Corid actually has to be given longer than you would think. You want to start them off at two teaspoons per gallon for three to five days, then go to 1/2 teaspoon a gallon for 7-14 more days.

Just reduce the dosage of Corid to 10 ml per each gallon, or 5 ml per 2 quarts. You can also dose the chicks with undiluted Corid 0.1 ml per pound of weight twice a day to give an extra boost. Are the chickens drinking the treated water? Some strains of coccidia are more serious. If they are not getting better after 2-3 days, you may need to switch to another treatment, such as toltrazuril or sulfadimethoxine. I will tag @casportpony, since she is more familiar with those meds.

As far as I know Corid is fairly safe and hard to overdose, stick with it and best of luck!

Thank you. That makes me feel a little better. I’m just worried about my girls! I know there’s no way anyone can tell me that they will be just fine, but I wish they would.

Her source on the dosing is quoted in the article, and it's the manufacturer, FDA, and FARAD that recommend it.

This is a standard treatment using the maximum dosage for 5-7 days, and the reduced dosage for an additional 5 days:

Thank you!
I spent my entire day today with one chick or another on my lap, making sure they each drank a whole syringe of (properly) treated water, ate some feed, and pooped so I could monitor.

Well, at least we know that you can majorly overdose your hens and they will be fine haha

Welcome to BYC! Since Corid is so nasty tasting they probably didn't drink enough for it to be harmful, so I think you'll be okay. You should also know that when I spoke with a technical person at the mfg they assured me it was almost impossible to overdose them on.

Do follow the instructions that @Eggcessive and @Pyxis recommended, they are correct.
