I went into my chicken house tonight and my one chicken looks a bit off and is sneezing/coughing, what do I do? Update: she stopped sneezing/coughing, but should still be concerned?

Could have been from dust, feed or ammonia. Make sure they have plenty of ventilation.
I would just observe and listen for a few days to see if she still has any symptoms.
