Oh geez.. I have one that is a MAJOR frog hunter..she trolls the edges of my pond on a mission for so long it’s crazy..and when she gets a frog..look out! So, who knows..plus, my other ones get in and then love to groom next to it for hours..so, still making use of it..here’s a picture of some frogersMuscovy don't do ponds usually. I have one and she doesn't even bother with it. She would rather walk on the grass than get wet.
