WE HAVE A 5 ACRE LAKE IN OUR BACK YARD AND PRESENTLY HAVE CALL DUCKS. THEIR WINGS HAVE BEEN CLIPPED. WE FEED THEM CORN DAILY BUT OTHER THAN THAT THEY ARE ON THEIR OWN. WE STARTED WITH 14 AND ARE NOW DOWN TO 5. I WAS WONDERING IF I'D HAVE BETTER LUCK WITH SOMETHING LARGER, LIKE SWANS. WE HAVE WILD GEESE WHO RAISE THEIR YOUNG HERE AND HANG AROUND THE NEIGHBORHOOD YEAR ROUND. WILL HAVING SWANS WORK OUT HERE? WHAT WOULD I HAVE TO DO? THANKS
