Limping and red skin

[RosyChickens]

Noticed my Foxy chicken limping
At a quick glance I didn’t notice much wrong, she has some newer feathers on her belly. And I noticed some red angry skin right around the base is the feathers. Should I be concerned?
She’sa golden sex link about 3 years old, free range, head of the flock of 5, though my bantam who has chicks right now has been sassy lately.

Have you checked her feet? And the belly feathers might be a brood patch.
