My EE hen Alma is ill again this morning. She's listless and her vent is pulsating. She had stopped laying eggs last fall, though she's only about 18 months old. She was never a good layer. She'd lay soft shelled eggs or fart eggs most of the time. Then one day she started with this. This is probably the fourth time I've seen her behave this way. Sometimes a clear watery poop, with listless behavior, pulsating vent and panting. In the past she's recovered in 24 hours. I just hope she'll recover again this time. I've separated her with some water to drink. She's just laying there panting. Is she an internal layer or is something else wrong with her?
