I came home tonight to a sneezing and wheezing hen. She is about 2 or 3 years old. She has NO discharge from anywhere. She is NOT lethargic. I have her in her own coop so I will know more about her poop and if she is eating, etc. I looked up CRD and synovitis....but they don't seem to fit the bill. Any suggestions? I am new to this website and hope I can figure out how to use it fully. Thanks for you help.
