Hen with large fluid sounding bladder covering her chest!

[olinandkim]

We bought a new hen and when we got home with her she has a large fluid feeling/sounding bladder covering her entire chest. She eats and acts natural, not in pain even when touching her chest. Noted her feathers are gone tonight on growth. HELP!!!!!
