Moaning, barking

[metzbower]

One of my Rhode Island chickens started up with moaning and barking this morning. She is over a yr old, and is moaning with every breath. Every couple of minutes, she "barks". Other than that, I don't see anything wrong with her. She is laying, and running around and eating with the others. (they all freerange)

Any ideas or things I should check for?

Oh and she moans with her mouth closed. Don't know if that's important or not...

It sounds respiratory. Hopefully someone who has seen those symptoms before will respond.
