Our little bantam Floofy is suddenly making whistling noises during both inhale and exhale. I can't see any obstructions but she won't really hold still for me to look down her throat. Her nostrils (are they called nostrils? IDK) seem clear. Anyone know what might be going on? It happened overnight. Is there anything I can do to diagnose it and/or alleviate this? She is such a sweet little girl and I want her to be happy, healthy. She's about 7 months old and just started laying the cutest tiny eggs.
