I just got a new hen at a local swap this past weekend. She didn't seem to be sneezing when I bought her but now that I have her at home.......... She sneezes alot & seems to be having a hard time breathing. She opens her beak when she breaths. She does not have a runny nose or any discharge or bubbles from her eyes. It is not infectious coryza (i have experience with that). Does any one have any ideas?
