I have a 6 month old golden comet hen that isn't feeling so well. She seems lethargic and spends most of the time laying down. When she is up, she is kind of hunched over and carries her tail low. I have also found a giant poop that is about 2 inches long and almost the same width. It is quite solid and dry feeling. Maybe she is just a little backed up (not drinking enough) or maybe has some sort of egg problems. Her vent area is clean and dry. She is still eating and drinking, but not as much as usual.
