Causes for wheezing and sneezing

[WannabeHomsteader]

Okay y'all, I have a 2yo ISA brown. A week ago, I noticed her comb looked a smidge discolored (she had frostbite in the winter on the same area of her comb, so I didn't think much of it). Three days ago, I heard her sneezing. Today I heard her loudly wheezing while inhaling (sounds like slurping the last bit of your drink through a straw). Her clucking is also raspy-sounding. She is eating, drinking, and seems fine apart from the breathing issues.

Her one single flockmate seems to have no signs of respiratory problems.

I can't check her over for additional symptoms right this minute, but I definitely will later.

Can anybody give me ideas as to what it COULD be? I'm not looking for anyone to diagnose for me (I know these symptoms are kinda vague), but I do need help with narrowing down. I've never dealt with respiratory stuff in my flock.

Note: she's always been a little raspy, but this is pretty pronounced.

Thanks to everyone - I have been STRUGGLING the last 2 months with flock health, and this site has been a wealth of info and help!!

Are there air bubbles in her eyes? @Eggcessive

Nope, no bubbles. After looking at her comb a few minutes ago, I am starting to think this could be a chronic problem, rather than an acute one. Her comb has been discolored for quite some time. So maybe it's not an infection? Except she sneezes, which makes me think it IS an infection...

Can you post any pictures of her and her comb? Do you see any bubbles or foam in either eye, or swollen eyelid? Does she sneeze mostly when she is eating, or all of the time? How is you coop ventilation? Dust and feed can irritate the nostrils, but if she sneezes all of the time, she might have a respiratory virus such as infectious bronchitis or a bacterial disease called MG. If she the only one with symptoms.
