Is there any way you can fence off the pool with a child's fence so that when the babies hatch, the don't go in the pool and get into the filters or drown when they can't get out? I think I've seen those kind of fences for sale somewhere. They keep young kids from falling in the pool. Then, when mama wants to move out her family, all you have to do is open your pool gate and mama will, hopefully, lead them to the pond.
