Hello everyone, I have a peahen who is sick. She doesn't have any nasal discharge, but she's breathing mostly through her mouth and sounds terribly congested in the lungs. Her energy seems good. She roosts in the rafters, eats and drinks. I've had her on a round of antibiotics (she's penned by herself in an infirmary pen) and have a heat lamp available if she wants to spend time under it, which she does sometimes. Do you know what she might have, and is there anything else I can do for her?
