My Khaki Campbell was wet from swimming and I guess he decided to sun himself. It was sunny yesterday but very cold. When i went to check on everyone in the afternoon he was frozen to the ground and could not get up. I kept pouring warm water around him until he was free. I am so glad that is all it was. at first I did not know what was wrong with him. SO BEWARE your ducks do not become stuck and become predator food!
