A neighbour arrived with a 1 - 3 day old wild mallard duckling yesterday. It was found in their paddock with no mother or siblings in site. I noticed that it had a splayed leg, this morning both legs were splayed. Tonight when I was preparing him for bed I noticed that his one side was very bloated, spongy to the touch. A few hours have passed now and the other side is also blowing up. It feels like trapped air. Can anyone tell me how to help this poor little abandoned duckling. Urgent help would be appreciated... thank you.
