I'm new to chicken keeping I've had my first small flock for almost 2 months now. One of my hens (called Wolverine- wasn't my name choice!! Haha) has started sneezing constantly, like every few seconds, and she will also do something that looks and sounds like a mix between a cough and a choke. I put my ear against her back last night and her breathing was very raspy. She isn't off her food or water and she's got plenty of energy still. I did change the type of straw I used a few weeks ago and just wondering if that may be contributing to it....? The other two, Batman and Bruce Lee (again didn't choose the names!!) Seem absolutely fine. If anyone could shed some light on what may be causing it and how to help her it would be greatly appreciated!
