Hey everyone. Looking for some help and advice. I have a small flock of white leghorns and about 4 of them have started to sneeze within the past week. Someone told me not to worry because we had just transferred them into a new larger coop and it was probably just from the dust. But it's not getting better. . There doesn't seem to be anything else wrong, no discharge, eating, laying and playing like normal....just sneezing. What should I do next?
