I have some newly hatched ducklings about a week old. One of them has a bill that is longer at the bottom than it's top and it sticks out slightly. Is this something to be worried about? If anyone knows if there's anything I can do to help him it'd be appreciated! Is this a natural formation or did I do something wrong? This is my first time one of my ducks has hatched ducklings so I'm pretty new at this.
