Dying rooster

[whispurr]

I hope that you will send his body to your state vet for Mareks testing. That is the only way to know if it was Mareks causing his lameness, and they also can look for other reasons. Bodies should be kept cold, not frozen, and taken to the lab M-F. This lis below has all of the state vet contact info:

If he had Mareks, the disease is spread through dust and dander, which is everywhere around your coop, home and land. It is unknown how long Mareks can remain in your environment, months to years, so that could effect any new chicks.w

Mareks is a virus spread through feather dander. It is not always fatal. It can cause 4 types of symptoms including nerve paralysis, skin tumors, organ tumors, and eye changes including blindness. A chicken might just have one type of symptoms. Sorry for your loss.

If my chickens have Marecks disease, can we vaccinate new chicks and they'll be fine?
