Hi, for the past few days I can see she keeps lifting her right leg up in the air. She keeps it only slightly higher so it's not touching anything and her toes are open. I can see she's slightly bent over to her left side keeping her weight there. For the past year she's actually been laying eggs (she's alone) and she's about 10 years old. Could she have arthritis? There don't seem to be any cuts or anything else on her leg but I'm really worried and I don't want her to be in pain. Is there something I can do for her?
