One bird LITERALLY has not been able to stand up in 2 weeks. Her right leg is completely paralyzed, toes curled. Her left is almost completely paralyzed, usually splayed out behind her. She is open mouth panting half the time now, it has gotten progressively worse. She has no nasal drainage, no eye swelling, no sneezing, no symptoms of coryza. She still happily eats and drinks, but I feel so bad for her! She is seperated from everyone. The other has a limp, but can still get around. The third is completely fine, as of now.
Pictures and videos I have found online of other chickens with Mareks look VERY similar to the symptoms she's exhibiting. I'm just worried because this man had, and sold, a TON of chicks that day, and if this is Mareks, a lot of people could lose a lot of birds.
They are on Grower feed. They are approx 3 months old. Mites have been gone for a few months now, that happened in the very beginning. The paralysis is as of just a few weeks ago, coming out of nowhere and getting progressively worse as the days go by.
The man we bought them from was from Massachusetts, older gentleman, wearing an apron. Lots of pens, lots of chicks, and some ducklings.
