Coughing - extended neck for a gasp of air

[babycharmed]

2 of my hens will cough and sneeze, soon after they will extend neck and head straight in the air (as if in pain) and gasp for air. This goes on all day and both are not eating well.
I looked down the throat and see no worms.
dust is not the problem and the coops are clean.
all have fresh water and feed.
they are sex-links and are 1year old.
Can anyone help? Thanks

Possibly IB? Have you seen this article?

Lots more info available on the web, but this is a good overview.

Good luck.
