Weird breathing in chicken

[IndioHatch07]

I have this 2 year old bird and I caught him tonight "snoring." I thought that's just what was happening but I also found out after looking that they don't snore. I'm curious as to what could be going on because it's been happening for a long while and he does not match any of the symptoms except that rattling kind of breathing. Here's a video of it. !!!Audio up. Hard to hear!!

Thank you in advance!

Sounds more like he's growling because he hears something outside.

He does growl all the time at us and the other chickens. I'm just worried because he sneezes a little bit more than the rest.

Check his nostrils to make sure they aren't clogged up with feed.

Thank you! His nostrils are clear, so he must've been growling at us.
