Base of chicken comb is grey.

Hello, I’m new here and this is my first post! So basically one of my chickens who is getting on a bit (maybe 6 or 7 years old) has gradually been getting a greyer comb. It’s more at the base but I was just wondering if this is because of her age or if she needs any more minerals. These are some photos of her comb. Thanks in advance!

It appears she may not be in hormones. Has she stopped laying?

How is her behavior? That tells us more than the color of a comb. If she's lethargic, perhaps making noises when she breathes, she may have an underlying health issue such as tumors or a chronic reproductive infection.

What is the state of her poop?

Thanks for responding.
Yes, I think lately she has stopped laying which may explain things. She is acting perfectly normal, eating with the rest of the chickens, coming into the garden, flying ect.
I haven’t seen her poop in particular as there are 10 of them so a bit hard to tell who’s whose, but I haven’t noticed any odd ones.
