I have a one year old hen, a few days ago I noticed she was off by herself, in the middle of the day on the outside perch. I approached and started talking to her, she had her head tucked and seemed asleep, deep sleep. I touched her and scared the crap out of her, I guess she woke up. She only opened one eye. The rest of the flock was out, and eventually she went out and forged with them. The next day it was the same thing, lethargic, one eye closed and kept opening her beak like she was yawning and couldn't quite get it out. Someone suggested she was eggbound, I have isolated her, given her a soaking in warm water for 15 minutes, felt her abdomen for an egg. I dont think she is eggbound, since this has persisted for three days. any ideas? I have her isolated in her own cage away from the flock, no other hens are exhibiting these symptoms.
