Chicken down

[Wyorp Rock]

She passed, so we sent her off for necropsy.

I'm sorry to read this. Let us know what you find out.

I'm so sorry for your loss! We're here for you.

Here is a report I just received from the necropsy. I don’t know what it means as far as pointing to a certain disease, but the chicken obviously had some issues.

Look at the end of the report. Do you see a summary? This sounds like it could be avian lymphoid leucosis.

It just says it found common cancer tumors on organs. The type is consistent with leucosis, but you need to follow up with the lab to find out if the type of cancer, in their opinion, points to lymphoid leucosis. This is very important you do this as lymphoid leucosis is a common yet seriously contagious virus that, if this is what the lab suspects, it has implications for the remainder of your flock.

Also, you might ask if the liver was significantly enlarged. That's one of the most common markers for leucosis.

I'm glad you are getting some information in. Looks like it's the preliminary report, usually you will get a final report that may give you a more conclusive diagnosis.

I agree with what @azygous post, following up with the lab will be important so you can have a better understanding of what you are dealing with.

Final report : Marek’s. And these chickens were vaccinated from a reputable hatchery. The report recommended vaccinations for the remaining chickens, but I’ve no idea on vaccinating adults against Marek’s. I’ve read that doesn’t help. Any suggestions? We are deep cleaning the coop and sanitizing with Clorox and raking out the chicken yard, but considering these chickens are pasture range during the day, I’m not sure there is anything I can do.

Sorry to hear this.

I'm not sure if Clorox will help with Marek's or not. You can use Virkon S.
My understanding is once you have Marek's within a flock, often the best you can do is manage symptoms and cull the ones that become very ill. While not ideal, it's one way to manage the disease.

Most with Marek's+ flocks do have chicks vaccinated or vaccinate themselves, not sure how much that helps. Chicks need to be quarantined away from the flock for a couple of weeks so hopefully the vaccine can help build in the system. The Vaccine does not prevent infection from the Virus, it may help stop the formation of tumors, so many folks do find that their vaccinated flock(s) still become sick.
