At a loss with this sickness

[Wyorp Rock]

Are they housed with the others are in their own flock?
Have you looked inside their beaks for any signs of canker, mucous, lesions?

Odd that it's just one breed. Unless they are housed separately from the others, eat something different, range or roam in a different place, etc. Do you have video of what they look and sound like? For video, upload to youtube and provide a link.

Have you tried any type of treatment whatsoever to see if they get better? (Antibiotics, dewormer, etc.)?

Here's a good detailed video of necropsy.

Unfortunately, TSC is less than reliable with their chicks, they may have gotten them from Murray McMurray, or they could have gotten them from another hatchery. It also could be that the reason only the wyandottes are having issues is because they had a bad hatch. If hatchery conditions for that particular hatch weren't up to standards, the chicks would have a weakened immune system making that particular bunch more susceptible to disease. Whatever it is, all your birds were probably exposed, but the others had strong enough immune systems to fight it off. Also note, unfortunately, according to the official TSC Facebook page, they do not purchase vaccinated chicks. They claim it is for customers that want to raise organic birds, which is absolutely ridiculous since the organic guidelines state that vaccines are allowed. Pretty sure the actual reason is it costs more.

If I'm not mistaken, one TSC could get birds from multiple hatcheries. At least that was the case 2 years ago. I know that whenever I was trying to figure out the bantam breeds one of my local TSC had, I asked for the hatchery name that sent those birds and then looked up the hatchery to find the breeds they deal with, which proved to work nicely. I imagine you have to be dealing with manager that will be professional enough to take the time and actually check the invoice for accurate information. This particular manager had to check the invoice because he had received birds from multiple sources within days of receiving the bantams.

I believe that currently almost all TSC chicks gone from Hoovers. If you buy them in the store @FeatheredFriends&Horses2 is correct they are not vaccinated. If you order from TSC online they definitely come from Hoovers and you can call before they ship if you want them vaccinated for Marek's or Cocci at no extra charge. They told me at my store they switched to Hoovers a year or two ago due to high mortality rates from their previous hatchery.

Depends on the location of TSC, but mostly they use Hoover's.
Birds are not vaccinated.
Afik, Hoover's does not offer the Coccidial vaccine, they will however vaccinate chicks for Marek's if you order them and request it (extra charge).

The Marek's vaccine does not prevent infection from the virus, so birds can still become sick. It may help lessen the formation of tumors.

Really the only way to know what's happening with the OP's birds is through necropsy.

Can sickness or viruses target only ONE breed? Im at a loss with whatever os effecting my flock. My blue laced golden wyandottes have slowly died one by one. They first start to "sneeze" which then turns to a more violent "honk" and they begin to hide and stay away from the flock. They still eat and drink, but never stop with their "sneezing". Ive not noticed any liquid coming from their nasal passages or mouth. Ive had zero survivors so far so we've decided to cull when the "honking" begins so they don't die miserably and slowly. I know I need a necropsy to ultimately determine what's going on, but at this time I have zero means to do this. I'm at a loss with this. I have Orpingtons, mixed breeds, and EEs. None of them have shown these symptoms. Even the new chicks I've hatched have not shown anything. It's ONLY the wyandottes. They are not a year old yet but will be soon.
Does anyone have any insight??

We had the same problem with our tsc Wyandotte. They may just be a weaker breed???

They are all housed together. Even the chicks are in a pen in the same run.
Thank you for the video!

I've been wondering if someone else who has Wyandottes experienced the same thing. I've thought about starting a thread just to see if there's anyone else. It's boggled my mind a bit.
Did yours do the sneezing too?

With two people having issues with only their wyandottes, both almost certainly from the same hatchery, it is highly likely a problem with either the hatchery handling of those egg and chicks or a problem with the parent flock.

Are these birds the same age and color, by chance? If you know the hatchery TSC purchased from, you could call and ask them. They may be willing to help. Certainly can't hurt to try
