Hi all, I noticed a couple of days ago when I was holding one of my hens that she was exhaling in a very soft wheeze. She is eating, drinking, pooping normally and is laying eggs every other day which is her pattern. She free ranges as normal and is running around with the others. Tonight she appears to have a "hoarse" sound to her vocalizing- kind of like laryngitis. No nasal or eye discharge, cough or sneeze or anything like that. I thought I'd just kind of wait and see how she is over a few days, but I've also read on posts that chickens don't get colds - they get bad respiratory illnesses. So what should I do??
