I have a young silkie hen (about 3 mos old) who has been sneezing once in a while and is huddled up. She eats and drinks fine and has normal droppings. She tries to cuddle up and get warm next to the other chickens and does a lot of sleeping. There is no sign of any nasal/eye discharge. Can a chicken get a normal cold or is it more likely Bronchitis? This is strange b/c the hen is my daughters and she handles it alot. My daughter just got over what the doctor said was Adenovirus. I noticed in a book that chickens can get that same virus. I wonder if she caught it from my daughter?
