I have a 3yr old Americauna hen that starts to limp every "Once in a Blue Moon" however this time seems to be a little worse because she is actually holding the leg up and hopping around on one leg. I managed to get a hold of her this morning and looked at her entire leg, there is no swelling and nothing seems to be out of place. She has done this ever since she was a baby. Is this something I should be concerned about?
