Delaware hen breathing hard/wheezing

[catface]

My 1.5 year old Delly is wheezing and breathing hard as of this morning. She was fine last night at dark. She's acting completely normal and I can't find anything wrong with her. She's eating, drinking, begging for treats, and foraging around the yard like normal. Any ideas?

Welcome to BYC. Rattles or rales are more common in chicken respiratory diseases than wheezes. Is she wheezing when she exhales or inhales? Could she have something stuck in her throat? Does she have watery eyes or nasal mucus? Any eye swelling? Here is a list of common diseases--the ones to look at are ILT, MG, infectious bronchitis, and infectious coryza. Here's the link:

The wheezing is when she inhales. And no mucous or discharge that I can see but she also sneezed a bit. Thanks for the links.
