No, both male and femaes are white. A grey swan is probably an adolescent who hasn't gotten his/hers adult feathers yet.
Well yes it depends on the climate or place it was born of lives. Also in The Ugly Duckling book the ugly duckling was grey, it was probably because it had a large egg.

Most swans are born with gray or brown feathers. They gradually develop their iconic white feathers as they mature.
Baby swans are called as cygnets. Adult male swans are called as cobs while adult female swans are called as pens.
Male swans are often a bit larger than the females and have a thicker neck; the knob at the base of the male's upper bill is larger than the female's knob.
They all mate for life.
The male swan has a penis, the female does not. Birds don't have penises. They use cloacae, like reptiles, the entrances of which are pressed close together when mating.
Mute Swans have a white body.A brown neck.And orange or yellow beck. A female's beck is orange with a small knob.A male's beak is yellow.
Mute swans reproduce sexually, with the male inseminating the female. She then lays an average of 4 eggs, which the female takes care of for the 36 days it takes them to hatch.
They are swans (several species).Male is the cob.Female is the pen.Young are the cygnet.
A female swan is called a "pen." The males are called "cobs."
