I recently got baby chicks from a silkie breeder. After the first day of settling in, they've been sneezing and shaking their heads and expelling some kind of eye-juice. They're indoor chicks right now, and live in my room. It isn't dusty, and it's not just momentary sneezing from a dust bath or dusty food or pine shavings, it's constant sneezing, even outside of the brooder. Now I've started sneezing as well. What's happening??!
