Recently I had a rooster with leg issues. Well he died so I sent him in for a necropsy and the results came back today. The necropsy came back with a likely Marek's disease. The problem is that besides by pets these are my show birds that I breed and sell chicks and started birds. I feel that the best plan of action is to treat it like Marek's. I was thinking cull all the birds, disinfect every inch and object in my back yard, and start over. I plan on using Virkon S Disinfectant and Virucide, would this work on all surfaces (dirt, wood, sand, concrete, wire, plants, plastic metal, ect.) I am going to talk to the person that did the necropsy and ask for his opinion as well as yours. I was hoping to hear other breeder and showers experiance with Marek's in their flock. Also would I have to rebuild all coops? Note: My pens are right next to each other hints all birds being culled.
