Hens comb is turning pale at the tips

[Chickenkeeper24]

I noticed her comb has started to turn pale at the tips, so I was wondering if I should be concerned, and if there is anything I can do to help her. Besides keeping her distance from the rest of the flock, she seems to be acting normal, and is still eating and drinking.The photos are

a little blurry, but any help is greatly appreciated

Can you gather her up and examine the comb more closely and take some clear photos?

What's your weather been like the last month or so?

Has she been under a heat lamp, light or plate?

Does it wipe off?
