Buff Orpington that gets intermittent blue comb tips

[Laurie11111]

Hello all, I have a one year old Buff Orpington hen that intermittently has blue tips on her comb. She acts totally fine. Eats well, lays eggs, is social with the other hens. I know that often a blue comb signals breathing issues but she does not seem short of breath. Only pants when it is hot or when she is under stress. Comb does not get blue when she is in distress. I was thinking that maybe her nares are narrow??? Or a cardiac issue?? Would love some advice. Here's a photo of the back part of her comb a little dusky. It comes and goes randomly.

If a bird has a larger comb, blood pressure tends to rise and fall according to mood, if she's calm, they might be a little blue.

All of my Roos with bigger combs have this happen from time to time. It’s normal as long as it doesn’t STAY that way or the entire comb is discolored.

Thank you guys for your input. I am less inclined to worry now.
