Still dealing with this one hen with a bad leg/foot. It is SEVERELY swollen right now, so I'm not surprised that she won't walk on it. But when she tries to walk, she acts like she can't quite feel that foot. She hobbles, and puts it almost too far in front of her. If she hits something like a fold in the blanket on my bed, she won't pick it up any further, and that is usually when she trips and tumbles over. That would technically be a sign of paralysis. So I would think Marek's. But there are some things still making me think otherwise. First, she's the offspring of two of my other chickens. And ALL adult chickens were vaccinated. Their offspring (the ones that stayed with me) were not (the ones I sold were vaccinated). Any NEW chicks or chickens coming in to my flock, get vaccinated. But I haven't gotten any new chicks or chickens, aside from hatching my own eggs from my own flock, since May. This girl hatched in April, and is now 7 months old. If she was going to develop Marek's, wouldn't she have become infected before now? Wouldn't she have become paralyzed or show some type of other symptom long before now? Or is it possible to hold the virus for 7 months, and THEN become infected?
