I'm a newbie - to chicken keeping AND Backyard Chickens. I got my first hens and a rooster just 4 days ago. The two silkie hens (who are not laying yet) are making this coughing/sneezing sort of noise. Remember, I'm new! So how do I know if this is a normal sound or if it's a symptom of an illness? Sometimes they shake their heads, too. I was standing outside the coop last night after they had roosted. I could hear them making that noise. Any help or advice is appreciated. (I'm still trying to figure out chicken language: when to say hen or pullet, rooster or cockeral, chicken or "banty" as they're called where I live, coop or chicken house!)I'm reading and trying to learn.
