I picked up my hen Hamburger an Easter egger and held her with her head slanted a little (because of how I held her) and I saw she has bubbles in her eye. I couldn't look in the other because she was so percistant on going back to the dust bath. I've only noticed her with the bubbles in her eye. I've also heard ocasional sneezing from some of my hens and a few at night have drippy noses- they've had that for a while. Here's a pic of her eye... Otherwise she and all my hens seem healthy and active.
