Have been prepping the pool for the arrival of the grandkids tonight. I was just about there, only to wake up this morning to 2 drake and 1 hen Mallard in the pool. I have pigeon proofed the pool, but haven't figured out how to keep ducks out of the pool in the spring. Of course, they have all shat in the pool. I guess it is SLAM time. My main planned community saw fit to have a park with lagoons about a mile away which attracts both ducks and geese who seem to Crud all over the park lawns ( great panning idea!) Maybe I could stretch a net over the pool in the spring before I start to use it to keep the ducks out?
