I have two 6 week old americaunas. They are in a wire rabbit cage until they are big enough to go out with my other hens. During the day the cage rests on grass, at night the cage is on a pile of aspen chips. There is also some newspaper in the cage so they don't just walk on wire. This morning when I went to move the cage one of the chicks couldn't walk. She could sort of stand but was staggering and stumbling around when she tried to walk. Her tail is pointing down also. I examined her and didn't see any lumps or bumps on her legs or feet. No broken bones. As I held her on her back and probed her feet she would use one foot to grab my finger but the other foot did not. It seems like one of her legs just isn't working very well. So, now with the leg seeming weak and the tail pointing down limply, does this seem like it could be early Mareks? There is always a chance that she got a toe caught in the wire when the cage got moved - I couldn't rule it out for sure, but it doesn't seem like that is the problem.
