I have a 15 month old Auracona hen that is otherwise healthy who started wheezing severely tomight and I though she was going to die in my arms. I rinsed her out with water and coaxed her back to life but it was touch and go for a while. I emptied her crop by flushing it but her lungs sound congested. Can I usa an antihistimine or is there a more natural way to get her to stop wheezing?
