Help with sick Cochen chick

[Wyorp Rock]

Her whole body smells.. but yes, I noticed (what I thought was her breath) to smell really bad. Since the vetRX, i dont notice that bad smell much anyone. She eats and drinks great, she also moves around a lot on her own.

Can you tell if the smell is just from getting soiled or is it more like infection?

With chickens it's hard to know how long a recovery may take. A lot depends on exactly what's going on with them. Some can recover quickly, while some do decline no matter what. Take it day by day and see how it goes.
