if you have snapping turtles then you absolutely want to keep any goslings away from that pond. If you want to know what a snapping turtle can do the a goose or gosling just go out to your pond and try to catch it/one by hand. Oh and be sure to take a first aid kit along with you. Snapping turtles can easily and seriously bite/cut a human hand or foot thinking it is food. Larger stapping turtles (which can exceed 30 pounds in weight) can easily sever a toe or finger. So, just think about your beloved geese or their goslings having their leg bitten off or even worse, having their stomach ripped open and being eaten at while they are still alive.Yes, we have a big pond (covers 1-2 acres). I have had her for 15 years, but she and her mate are not "friendly" with people. They have never been enclosed and won't even let me near them. The closest they come to me is about 20 feet away if I am throwing corn out.
I hope snapping turtles don't get them! That would be sad!
do your research and get rid of the turtles before you allow your goose brood to venture into your pond.
