Jersey Giant Hen missing feathers

[MicheleE]

My Jersey Giant hen is missing feathers from her chest. They have been missing for a while and the skin looks pretty smooth. Obviously she is surviving the weather but does anyone know why this happens. She is not picked on - quite the contrary she is the defender of the flock.

Might she be going broody? They pluck their feathers in the area where the eggs will make contact with their skin.

That might be it. Thank you!
