I have an approximately 18 week old Easter Egger that is wheezing with every breath she takes. She looks normal and is acting normal. I let them out of the coop this morning around 6:30 and she was fine. My kids went out around 11:30 this am and noticed this. The wheezing is quite loud. She was in the corner taking a dust bath and I could hear her when I walked into the coop. Should I be worried?? Is there anything I should do?? I did look at her nose and throat and didn't see anything out of the ordinary.
