I have a 3 year old barred rock hen who is wheezing. She seems to breathe in okay but makes such a sad noise when breathing out. She looks perfectly fine - bright, alert, tail up, no discharge anywhere. She's eating, drinking, perfectly happy. I just got her, along with her 5 sisters, from a friend Saturday and the noise was very noticable Sunday morning although nothing on Saturday. I believe my friend when she says none of the hens made a noise before coming here. The other 5 are fine. We have her inside in a warm room, with food and water and are using Vet RX and a vaporizer. Any further ideas? The noise just seems to come from her nose or face - it doesn't seem to be down in her chest. She is not coughing or sneezing or gaping her mouth. My husband thinks she is quiet when calm and louder when we are handling her.
