Swollen breast with fleshy spots

[pilotswife]

Hi everyone! This one is stumping me but I'm still fairly new to chickens so I'm hoping y'all can help. I have a hen, around 18 mos old, that has a swollen breast down to her legs. I know that can happen after a day of eating but I think there's more to this. She also has two fleshy spots, one at the top of her breast, the other down towards her legs (maybe stomach area?) that aren't raw flesh, more like red, wrinkly flesh. It's hard to explain. She's acting fine. Eating and drinking. Curious if it's a tumor or something I should be really concerned about. I know chickens can have cardiovascular issues and that's what first came to mind. Thanks in advance for your thoughts!

Perhaps shes starting to molt and her skin is just a little irritated? I'm not sure though. Sure hope its nothing serious.
