My Indian Runner is favoring her left foot. She can use it, but will not put it down or put weight on it. There is no sign of outer damage. The joint where all the toes meet the leg is swollen and tender. The vet has offered to x-ray it and splint it, but at the tune of $220.00!!! When my toe was broken the doctor said there's nothing that could be done except to keep it still and wait for it to heal. how does one do that with a duck?
