Two weeks ago my female Rouen wS fine in the morning layer her egg and was hanging around with my other 17 ducks and chickens. They free range. I'm not sure if she was hurt by mating or by my 3 yr old son by accident. But she can stand and use her legs but when she tries to walk forward she just falls onto her chest. I put her up that day and separated her from every one else. She eats and drinks well. Two days later she was walking much better but then she started having trouble again. They have plenty of niacin and vitamins and food. She isn't getting better and I don't know what do. I can't take to a vet right now but I can fix her if someone knows what's wrong
