I got the results back on the cultures from the necropsy. Again there was no signs of anything.
The state vet looked at the photos taken by Linzi as he was out the day I brought the bird to them.
It's possible it could be Infectious Laryngotracheitis (ILT). There looked to be some inflammation in the trachea but it was hard to tell. I put the bird in the fridge and not the freezer so it could have just been blood pooling in the trachea walls. I've seen none of the symptoms of ILT. I pick up my birds everyday(not all of them) and get a close up of their faces and have seen nothing like this. Linzi said to keep an eye on them and to watch for blood in mucus and nasal discharge. The birds will shake their heads to "shake" the mucus out of their nose and throat.
These are symptoms of ILT.
- Dyspnoea.
- Gasping.
- Coughing of mucus and blood.
- Drop in egg production.
- Ocular discharge.
- Sinusitis.
- Nasal discharge

I may never know why this bird died but at least there has been disease/virus/bacteria ruled out and no worms.
