I've done enough research to realize it could be hundreds of things... I live in Louisiana, it's hot, but the chickens have plenty of shade & water. This is one of my friendly free range bantams, not in the coop, but in a flock of about 6 that cruise the yard and sleep on a shelf by the back door. Just started making this sneezing chirping sound 2 days ago. This morning noticed eyes appearing watery and squinting. Any probabilities, or what I might look for to treat..? Thanks in advance
