She does puff her feathers, but she has always tended to be broody in the fall. We gave her a couple of eggs to lay on, but she is a mess. She is missing a lot of feathers, and she is very thin. Her last molt was not like this one. I have never seen a chicken walk backwards and sideways like a drunken sailor. I dumped a bunch of food into the corner of her nesting box, hoping that she will eat more. Maybe that will help with the green bile. The poop, is huge, like a weeks worth all in one shot and the middle of it looks like a dried up gritty egg, but with no definite shape. I am thinking that she is due for a warm bath. Last time we had one of our Buffs having egg trouble, we bathed her and it seemed to clear things up. But like I said, they never did the weird walk. She is inside where I can keep an eye on her, but so far she remains the same.
