When we sneeze, it doesn't always mean that we're sick. Is that the same thing with chickens and Ducks? I was in the coop earlier putting new feed in their feeders and straw and their nest boxes. One of my chickens was in there with me. She sneezed 3 or 4 times. Is she sick? Or could the dust that flew up from the feed and straw maybe have gotten into her nostrils?
