My hen is sneezing lately and also sounds like there is fluid either in her lungs or in her throat, nose area. Is there anything that can be done and could something like this be contagious to the others? Could it be serious enough to kill her or could it just be a cold. It sounds like a person that has pneumonia when she purrs and sometimes when she breathes. She is roosting away from the others now, I was just curious what it could be and if it could be treated. Thanks!
