I have a crested white female duck who seems to have an injured foot. She seems to be hopping around with her one foot off the ground. When she does have to put her foot down she falls down. I am not sure how to treat this injury. Should I just let it heal on its own, bring her inside for a few days away from the other ducks, or try to find a vet? This is my first duck injury and any help would be greatly appreciated!
