Silkie is yawning non stop, help!

If I were you I wouldn't worry too much about your feed since no one else got sick.

There really are bacteria every where though, one can not get rid of it from everything.

No word back on the final necropsy report yet?

Unfortunately listeria can go symptomless for quite a long time, so if the feed is contaminated I do have cause for concern.

Not yet. I will post it as soon as I get it!

Just received the latest report, they suspect Mareks but have not received the testing results yet to confirm. 5 of my remaining birds are vaccinated, 1 is definitely not and the other 4 I’m not sure as I believe they came from TSC originally. I’m heartbroken and so very sad of this news.

I am sorry you lost birds and I am sorry this is the final report.
Marek's wears down their immune system and allows things (like coccidia and bacteria) to become out of hand.

Good luck with the rest of your birds.
I wish you the best.

I’ve been reading and reading and reading some more...I can’t understand how I’ve only lost 2 birds if it is in fact Mareks...wouldn’t the others be showing some signs by now? Although, I’m not sure there is another ailment that would present tumors that would be any less horrible than Mareks. I’m also annoyed at myself for pestering Cornell to send me results as they get them. I should have waited until all the testing was done!

Your vaccinated birds may never show actual symptoms.
Have you read how the vaccine doesn't prevent the disease but does prevent some symptoms?

There is a good article that explains the disease in the article section here.
I'll go find it and link it for you here now.
