Is it concerning?

[KikiDeAnime]

I noticed today that Colonel sounds like he's whistling through his nostrils. At first I didn't think much of it until I remembered that we've had chickens do that before they ending up dying.
I've tried to look it up through google but nothing comes up.

Should I be concerned if Colonel is doing this?

Can you get a video of him doing this? Any other symptoms like drainage from nares or eyes?

I've inspected him over but it's only the whistling.
I'll try to get a video but I'm not sure if you'll be able to hear it with how quiet it is.

It could just be him I have heard of ducklings making whistling noises even snoring they all can have their little quirks. If he hasn't other symptoms he's probably fine. But if you can get a video that would be great too.

I tried to get video but they both thought I brought treats so they started making a bunch of noise.

Treats first them video!

Possibly his nares are dry. Provide him deep water. Doesn't sound too serious.
