Chicken has had increasing lethargy over past few days. Lost willingness to eat today. Not egg bound: can't feel an egg, and until she stopped eating she was pooping semi-solid feces. She is now standing with her wings slightly out to her side. Her eyes are usually closed. About half the time her breathing is audible and her breaths seem to be quite deep. I have her inside. I swabbed her throat for gapeworms, but found none. Please help. She is only a year and a half old, so it isn't old age. Taking her to a vet is not an option unfortunately.
