I'm not very experienced or knowledgable about chickens, I've just had them since July...but I've had two chickens at two different times sneeze frequently for 10 days or so..they seemed absolutely fine otherwise, and it just passed on its own. It seemed like a "dust up my nose" kind of sneeze, but it was fairly frequent. Since they seemed 100% OK otherwise, i did nothing..and they are fine. I wouldn't rush to medicate if they seem normal otherwise.
There are occasions Drama sneezes, too. I've never worried about it. She's never given me a real reason to.
