My rescue duck is around 4 weeks old and is still making a peeping sound but sometimes I hear more of a honk. Could it be a respiratory problem or should I just relax? Because it was doing really well walking around, then I think it hurt his foot by trying to escape his cage a few days ago. The foot looks fine, no hot spots or anything. But now she doesn't want to walk around much and when she does, she falls on her back and can't get back up. Everything else is normal as far as I can tell. I am giving extra Niacin in her water and she isn't on medicated feed. But her feed is high protein (20%) but I added oats to it around 50% oats 50% feed. When my daughter wakes up I will try to get her to make a video so you can hear it.
