Chicken has soft swollen spot under beak

[LaFleche]

Both her feet look really swollen, does anyone know why and how to help her?

Does the swollen area feel soft or is it rather hard?

 

[Rose64]

The swelling feels firm but not rock hard, she doesnt flinch or have a strong reaction to having the swollen areas touched, the top of her head by her comb seems also slightly swollen, she has no wounds on her body.
