Problem with Chicken breathing

[zachstedman0103]

I seem to have a problem with a chickens breathing. It is very loud and noticeable and it doesn't seem to be moving around quite as usual. Its a Commercial Hybrid around 21 weeks old and not sure what's wrong as I've never had this before. Is anyone able to help?

Can you post a video of the chicken breathing?

Yes, a video would be helpful. Is she new? Does she currently lay yet? If so, when is the last time she’s laid? Sometimes loud breathing can be from straining of an egg bound hen or a respiratory disease. What kind of bedding are you using? Do you clean your coop frequently? Mold spores can cause pneumonia in chickens (Aspergillosis) can cause wheezing with loud noticeable breathing.
