One of my barred rock hens appears to have a respritory infection, likely from the weather. It has been cold, windy, and today it rained. I noticed it today when she hopped on the fence and she sneezed. Her eyes got bubbly, there was gooey snot around her nostrils and beak (when she opened and closed her beak), and she has this smell from her head. Smelled like.. You know that salty, stinky smell dogs sometimes get? Well that's what it smells like. She might not be seperated since in the winter a few pullets had similar symptoms so I'm guessing she caught it from them and it worsened with the weather. We don't have anywhere to put her also, either she sleeps with the hens or the pullets, stays in the coop or freeranges in the frontyard. It's up to her. A remedy of some sort would be highly appreciated.
