Here's what I would do, beginning right now, with as detailed arguments as to why ...
1. Replace their water with an astringent solution. Mix four teaspoons of (any) Apple Cider Vinegar to each gallon of water offered to all your birds (but NOT in galvanized metal containers).
Before anybody argues that it doesn't kill coccidia, or that it must have those trace amounts of enzyme folk call 'the mother' in it? I don't care, 'cause it's the acidity and the tannins that I'm lookin' for, primarily to strip the mucus from their systems, so as to improve nutrient/vitamin uptake, which also helps to boost their immune systems and allows them to better absorb any medication(s) given.
2. Give *something* right now, in absence of evidence to the contrary, rather than waiting for what you'd rather use. Preferably something that you haven't tried, based upon the Active Ingredient rather than Brand (i.e. if you are waiting for Corid, then you are waiting for just a specific brand-name of Amprolium, which you can pick up in multiple forms, and at multiple locations close by).
Based upon your other posts, now that I've been afforded the opportunity to read them, they're stuffed full of parasites ... that's why they're sick, and why their immune systems are failing ... for example, that's where all the Vitamin B1 they need is goin' to, and Corid (Amprolium) kills oocytes by blocking the uptake of thiamine (Vitamin B1), which further exaserbates the potential for deficiencies, when I'm reasonably certain they're currently sufferin' from.
Fenbendazole appears to the least likely to do any harm to chickens, despite the lack of FDA approval for the off-label use of, and has been well documented to still have no adverse effects upon the bird, even at 100 times the reccommended dosage levels (save for emerging feathers during molt). Now, there may be some reason for concerns over meat 'n egg consumption, but most folks that name their chickens have no intentions of frying/baking/boiling 'em any time soon. And, you're most probably not concerned about any potential to degrade the quality of your rooster's semen ... the point is that it ain't gonna really hurt 'em one bit.
And, in regard to FDA? >>PECK HERE<< to see the Freedom of Information Summary about the use of SAFE-GUARD in the feed of growing turkeys.
Or, better still? The PubMed.gov database, from within a document located at NIH.GOV, regarding it's use in Africa to treat parasites we're not very likely to find w/in our chickens:
Fenbendazole 4% (Panacur, Hoechst) administered in feed was used to treat chickens infected with Ascaridia galli, Heterakis gallinarum and Railletina spp. It was also used to treat Syngamus trachea in broiler birds. There was a marked drop in helminth egg counts in the faeces on the second day of treatment and the faeces became negative by the seventh day after the last treatment. Post-mortem examination 15 to 21 days later showed that the drug was 100% effective against Ascaridia galli and Heterakis gallinarum at 10 mg/kg. However, for complete removal of Railletina spp. 15 mg/kg was required. Similarly 20 mg/kg fenbendazole was effective against Syngamus trachea. It was concluded that fenbendazole is suitable for the treatment of the important intestinal and tracheal worms of poultry, a dose of 15 to 20 mg/kg for 3 consecutive days being recommended for use under field conditions.
IMPORTANT NOTICE: I'm no vet, and I ain't claiming that this will cure your birds of coccidiosis. Or, for that matter, that the Amprolium absolutely won't ... just sayin' I'd begin these first two treatments immediately, and that they won't do you or your chickens any harm.
Most medications intended to attack coccidia suggest leaving the litter unchanged, presuming the development of some level of immunity w/in younger birds. It is my suspicion, based upon your posts, that you're dealing w/ either different oocytes or that they have become resistant to treatment. Therefore, I would try 'n remove them (or, at least, reduce their numbers) from your flock's environment, and I think starting w/ a flush would be something worthy of consideration. As to the cleaning? I'd repeat the process often, as they're gonna spread 'em all over again before/during/after treatment.
For a better understanding of coccidiosis, read this document from Dr. Julie Helm of Clemson University (and anything else you can from her, as she's one fine champion for chickens everywhere ~'-)
