I went out to care for my ducks and found one of my male call ducks on his back. He was trying to trun over right side up, but could not. I took him inside and gave him water and food, but he will not eat or drink. He can stand, but he is very wobbly. About 3 days befor this, he had a crusty eye. I got medicine and it went away, so I put him back outside. Could they be connected? I just don't know what to do! He seemed was better, but now I just don't know! Can anyone help?!
