I though her pupil looked dilated also and yes all 3 birds lost were a year or younger. I listed Marek's as one of the possible causes of death on the lab intake form.I will post the results when they come in.

For anyone who may read this thread at some point in the future, the necropsy result points to plaques and lesions in the trachea caused by pox and fungal infection, but an underlying issue of Marek's Disease is suspected of immunosuppression, allowing these infections to thrive. Final confirmation of Marek's from lab testing is awaited.... cross reference the linked thread below regarding necropsy result
