Coccidia...

[Fullcrazy]

So 3 days ago I had 20 happy healthy active 8 week old chickens. 2 days ago I went to lock up the coop and found 2 dead. Saw coccidia poop, and started treatment next day, yesterday. 3 died overnight. 2 more have died today, and all are showing signs. I'm going to lose all 20 within 48 hours. This is absolutely heartbreaking, and I feel totally helpless. I've had chickens for 7 years and never had a coccidia problem. I'm devastated.

I'm so sorry.
What dose are you using (just to make sure it's correct)? You can also give them a dose orally for up to three days in addition to the medicated water. Dosing for that is here:

If they are not drinking well on their own then I would also give them the medicated water orally several times a day to make sure the medication is getting in them. There are some strains that are reportedly becoming resistant to amprolium (corid) and those strains may need a different medication, a sulfa antibiotic or toltrazuril. Corid has always been effective for me.

Some strains are more virulent than others, and can do more damage to the digestive tract quicker.
Correct Corid dosing is below, use the severe outbreak dosing:

I'm using the severe dose. They all were drinking, but they stop a few hours before they die. There are only about 5 that I have any hope for, but I'm not holding my breath that any will be alive by morning. Less than 72 hours from start to finish.
