For the past three days I have been feeding a new Mallard Mommy that had 10 cute little chickies following her around and Mom following me around to feed,..well tonight TWO are missing,...What happened? They are at the same college pond that Shorty and Rocky are at and I don't know if it could be turtles,..snakes,.do other birds (like geese ) go after them? One of the Mallard drake nipped at one and mom got right in there to set the record straight,..what can I do to help,..I can't see her lose all of them,..I went looking for them all night tonight but nothing,..?????
