open mouth breathig help!

[Shadowsfate]

My favorite roo has been an open mouth breather ever since I can remember, latley I have noticed his breath is stinkey.
also I have never heard him crow and he must be 5 or 6 months by now but could be just a late bloomer.
He makes a snoring noise when sleeping.
Besides that he is perfectly healthy, clear nostrals, bright eyes, pink comb, aware and alert, and has a healthy cage-mate.
Like I said he has been this way for a while with no other health issues... Is there something really wrong with him?

Any breathing issues..... And I always worry about gape worms.

Now, I haven't ever had any...(my poultry have never had them either).....but they are so disgusting...I guess I think about them a lot.
