Because I keep reading such great reviews about the toltrazuril for cocci, I think when you get it, you should stop the Corid and go with the Toltrazuril.
I just read a post on a goat forum and someone was asking "Does Corid Work" got the following reply....
The only product on the market that actually kills coccidia is toltrazuril (Baycox) or ponazuril (Marquis). All the other products, Corid, Di-Methox, Albon, just inhibit it and allow the goat to build an immunity to the protozoa.
and another person posted that corid is a coccistat not a coccicide, so Corid is more of a preventative medication, not really a cure.
In the Wormer & Cocci section under Corid: "Corid unlike sulfa's do not kill all lifecycles of coccidiosis."
So, I'm thinking just go with the Toltrazuril and be done with it.
...But I also would worry a little bit that if the Corid might stay in their system for another week or so after you stop giving it, and when you give the toltrazuril— would the overlapping drugs stress their systems or cause stomach upset? So, you might want try the Toltrazuril out first on one rabbit and make sure it doesn't react with the corrid in their system before giving it to the rest of the rabbits.
Here's the link to where those quotes about cocci, goats, Corid and Toltrazuril came from.

Also, there is a picture of a rabbit intestine showing signs of coccidiosis on this web page.

And if its NOT cocci, what else could it be? The guts are hugely swollen, black and purple and red, with greenish blackish staining in the flesh of the belly and even into the hide itself. I should have looked inside of the kit today but was so heartsick I just gave it to the woods but the one looking so very poorly right now shall be opened up and looked inside of later today.
With coccidiosis they say there can be white spots on the intestines like this photo.... but the white spots only show up for a few days and only in massive infections so if you don't see any white spots it doesn't really rule out cocci.

Another bacteria called clostridia causes symptoms that sound more similar to what you described— greenish viscera- so internal organs turn greenish, and corpses blow up so "swollen"...
Clostridium spiroforme has often been described in rabbits in recent years. This type of enteritis is common, mostly in well-fed animals (perhaps due to excess protein?). Both young and breeding animals may be affected. The diarrhoea is often very liquid and characteristically quick to putrefy.
The corpses are blown up and the autopsy reveals greenish viscera. Treatment aimed specifically at anaerobic bacteria can be effective (Dimetridazol, Tetracycline + Imidazol, etc.). ...Clostridia are hardly ever isolated in growing rabbits after weaning. Perhaps this is partly because these are anaerobic germs which require a battery of special techniques for isolation and identification.

The site mentioned above also has some good information about other bugs like e. coli. that can cause problems so might help you.
