She is a 4 year old golden comet but the first time I recall seeing one assume the shape of a ball. No extended neck, walks stiff and slowly and I now have her eat separately (but still in sight of the flock) as she eats a little, rests and then eats some more. No one is picking on her. But she is weak. She fell down this morning from just a touch and didn't try to get up. So we picked her up, set her by the plate as shown and she ate. Just seeking information on what this might be.... Thanking you in advance.
