I have an Amerucana chicken that is limping and doesn't use his foot. The age of it is abut 6 months. She is not lighter or heavier than the others. From morning to night, she wakes up and jumps down from her roost log. She is hopping on her right foot while lifting up her left foot. When I let all of my 4 chickens out, the other three run around the yard. My limping bird gets tired of trying to keep up with them so she just sits in the coop. She is still laying eggs though. Today is the second day of this symptom. No other birds are doing the same thing. There is no bleeding, but I don't know if their is any injury. I also don't know what could have happened. She is drinking normally and eating normally. The poop looks okay, just like normal. My mom feels her leg every day, and it seems to be hotter than her other leg. I don't know how to cure the problem. That is what I need responses for. When I get a picture, I will post it.
