I ordered ducks and chicks I got them yesterday the 14th. 2 ducks so far this has happened to. They were walking fine eating drinking then all of a sudden they would try to stand and walk and couldn't...just wiggle around, lay on their side and die? the brooder stays at a steady 95 degrees i clean it out once a day and they have plenty of food and water. the water has the save-a-chick electrolytes and minerals in it. I don't know what happening but I need help.
