Hi there! I have a pullet at about 15 weeks old. I noticed yesterday that she does not want to use her one leg. She keeps it tucked up when she stands and when trying to walk she uses it for a quick second....stumbles or steps on her bad foot....like she does not know its there. As I noticed this she was following the rest of the girls outside for a drink. Needless to say she stumbled and pretty much fell off down and off the ramp. It was sooo heartbreaking to watch.....thought maybe she hurt it jumping down from the perch, etc. I checked her leg and it doesn't seem swollen or broken. When I pick her up she seems to move her leg just fine but just not when she has to put weight on it. I have put her in a cage by herself with some water and food. Hoping she can just rest it without the other girls around. Does this sound like mareks??
