What is the difference between CRD and Coryza???

[Bedste]

Denagard is known to help with CRD but what if I give it to birds who have Coryza? What is the difference between Coryza and CRD? Anyone have any ideas?

Coryza is one of the many CRD's...just a general term for all of them. Here's a link with all the differences and possible treatments:
