I have 2, no 5 ducks on my lawn. The female, Selene, is a bit a screamer. When she really wants food she does the duck equivalent of "GIMME FOOD GIMME FOOD CAN"T YOU SEE I'M A POOR STARVING DUCK FEED ME!". At 6:30 am. On a weekend. My neighbors are probably really upset. Any ideas on how to stop them from quacking that early? Thanks!
