Celtic (or anyone that wants to chime in).... my duckies are now 3 weeks old and certain ones sound distinctly like whoopie cushions. How high are the chances that they are female?? The buyer who wants 2 girls/1 boy called and wants to come get them tomorrow and I could use the room in my brooder pen.
I'd go ahead and give them 2 whoopie cushion ducks and a quiet one. Just tell them to listen closely the next few weeks to be sure.
