What is the conflict in The Ugly Duckling?

The conflict is a nother duck's egg hatches and it is homely and is verbally and physically bullied. Even on it's own he is abused and isolated and cannot fly south for the winter because he is too small to fly. When Spring arrrives, he can no longer take this harrasment and lonliness and he throws himself into a flock of swans. But instead of being killed he finds out that he has grown into a big and beautiful swan.
