I have not read through the responses but here is some information you might find useful, for now or for the future if it isn't pertinent at the moment.I really hate to do this but is there anyone out there who could direct me to BYC articles or any for that matter that would deal with a form of Coccidiosis that shows paralysis and doesn't respond to 3 seperate courses of Corid and finally a full treatment of Sulmet. All of these birds have been wormed with Safeguard as well.
I just received a call from the Vet who did a necropsy on one of my birds I believed had Marek's because of the paralysis that kept showing up in the birds I have lost. I mean textbook, one leg forward and one leg back paralysis. One bird pulled out of a mild case, only one leg involved but in the second bout, a month later, she succumbed to what I believe was the occular form of Marek's. Lumps around the eyes that had not been there before and blindness. According to this Vet's findings, it is either the food is not giving the proper nutrition or it's coccidios.

"A vitamin B2 deficiency can be mistaken for Marek's disease since both have enlarged peripheral nerves." from

here's an eye link
Some vets will do a fecal float test for coccidiosis for a small fee.
I just wanted you to have these links if necessary and do not know what the diagnosis is. I am sorry for your losses. Also you might want to think about botulism- here is info and link:
"Clinical signs in poultry and wild birds are similar. Flaccid paralysis of the legs, wings, neck, and eyelids is seen. Paralytic signs progress cranially from the legs to include the wings, neck, and eyelids. “Limberneck,” the common name of botulism, describes neck paralysis. In affected waterfowl, neck paralysis can lead to drowning. Affected chickens have ruffled feathers. Signs in broiler chickens may also include diarrhea with excess urates in the loose droppings.
