I posted this yesterday but did not get any responses. I have a 3 yr old Americauna hen and since the day we got her she would limp every "once in a blue moon" but this time it seems worse because now she wants to hold the leg under her and try to hop on the other leg. I have never seen it like this. I did get a hold of her and checked the leg, there is no swelling and it seems to all be in order. So should I be concerned that something else is going on?
