Sneezing and Coughing Chickens - help?

[Mheusser]

I have one of my pens of birds that started sneezing a week or so ago. It's been really wet here so I figured it was allergy or a cold. They eat and lay well. A few of them started coughing and rattling but again no discharge and acting normal. We have used VetRx and started them on Tylan 200. Any other suggestions?

I don't know the answer, there are a number of possibilities, but I hope this thread will help
