My ducks are scared of everything. I don't understand. They have a big pool to play in and they have been in it and has so much fun, but now they won't go near it. I can hardly get them out of there coop. They have a fenced in area that is safe from predators. I just don't understand. I give them lettuce, in fact I throw it right at them and they are to scared to eat it. Their scared to do anything. What do I do? I feel so bad.
