From Mercks Vet Manual:
" Avian encephalomyelitis is a worldwide viral disease of Japanese quail, turkeys, chickens, and pheasants, characterized by ataxia and tremor of the head, neck, and limbs. Ducklings, pigeons, and guinea fowl are susceptible to experimental infection. The causative picornavirus can be grown in chicken embryos from nonimmune hens. It is transmitted for ~1 wk through a portion of eggs laid by infected hens, and then spreads laterally in the hatcher or brooder to susceptible hatchmates.
Clinical Findings:
Signs commonly appear at 7-10 days of age, although they may be present at hatching or delayed for several weeks. The main signs are unsteadiness, sitting on hocks, paresis, and even complete inability to move. Muscular tremors are best seen after exercising the bird; holding the bird on its back in the cupped hand helps in detection. Typically, about 5% of the flock is affected, although morbidity and mortality may be much higher. The disease in adult birds is inapparent except for a transient drop in egg production. The disease in turkeys is often milder than in chickens."

This would explain why they are OK for a week or more,then start showing signs. Also why unvaxed chicks are showing the same signs.
Hope the vets find out what it is SOON!
