I don't know what it is but I would research Marek's. You can treat Marek's to an extent.

You mentioned unable to stand, but do the legs move/kick? Sounds like toxin or botulism based on the sudden death. Any recent chemicals, fertilizers, access to decaying material?

I've never heard of Mareks presenting with neck symptoms, but I probably wouldn't rule it out due to the age.

If this happened to more than one bird, I would seriously consider a necropsy to identify the cause of death and any potential diseases.

sounds like seizures, maybe poison since they died so fast.
