Hi all, We originally had two hens that just started laying. We raised these from day-olds and they were vaccinated for Marek's etc. All things were going well, so we decided to enlarge our flock! We picked up 5 more laying hens from a woman who inherited them from her mother. One looked in particularly rough shape, but she was a frizzled cochin that we thought we could nurse back to health. One week after we had her, she went downhill terribly, and we culled her. About 2 weeks later one of the rescued hens stopped laying and then began looking depressed and droopy. Finally, she could barely hold her head up and stopped eating and drinking. Because we had no idea what we were dealing with, we took her to the closest state agriculture laboratory and had a necropsy done. The results came back with a high level of ascarids and caprillaria (roundworms) and low levels of coccidia. The histology report also found "neuronal lesions indicative of Marek's disease." Well, everything we have looked up on Marek's disease seems devastating. We can easily treat for the internal parasites, but nothing to do for the Marek's. What should we do? Some sites suggest culling the entire flock, decontaminating the coop and living area, and starting from scratch next season with vacinated chicks. Any suggestions? Any help? We would hate to have to start over, but we also understand that this is part of what we signed up for by raising backyard chickens. Thanks in advance.
