We have a pair of 4mth old mute swans. We have had them for about 6 weeks and they have been doing really well until a few days ago. The one swan is having great difficulty getting to a standing position. Once it is standing it is fine but it doesn't really walk around very much and like I said really struggles to get to a standing position. I am worried it hurt its leg and wondering what if anything I can or should do about it.
