Respiratory infection?

My corn is making clicking sounds when she exhales. Could she have a respiratory infection?
It sounds sort of like the sound a human makes when they're breathing through a partially blocked nose

What should I do?

Is a trip to the vet in order?

yeah i would either take it to a vet, or i think i heard that if you raise the temp really high it gives them a kind of fever and can fix an RI....but im not positive so maybe somebody who knows more about this can help you out

Yup, time for a trip to the vet.

Definitely a vet trip, higher temps can aggravate the condition and dry out their sinuses.
