My little serama roo is breathing a bit heavy, though not really bad. His breathing sounds raspy even when I listen to his lungs. He's so congested and I feel sorry for him. No snot, but lots of mouth breathing. My chickens sometimes get like this in the wet cold winter around here. This roo hasn't learned how to stay dry yet. Is there anything I can do? Like vapo rub and hot steam, but the chicken equivilant? My chickens are like my children, so I want to care for him while he's sick.
