Purple comb

[Sisterhens]

My yr old leghorn hen has developed a small purple portion on her comb. Otherwise eating/drinking well,laying everyday,interacting w/her 3 sisters(all younger) the same. I clean the coop and run every other day, she isn’t wheezing. She has cool clean water to cool in.
Everything I research seems extreme and doesn’t feel like it applies. Am I missing something?
Any help would be appreciated.
I’m new to this.
Thanks!

Hello and welcome to BYC!
Could you get some pictures?

Thank you! I’ll try. It’s pretty faint and low underneath toward the back.

Its probably like that because the comb is so big and flopping over its circulation is cut off.
