I'm a worried first time hen owner. My Cornelia is a Red Star, approx 8-10 months old (she's a rescue, so I'm guesstimating based on when she started laying). She's been free range the seven months she's been living with me, and started laying in April. For the past few weeks, she hasn't laid in the henhouse. We found a few eggs at the beginning of this behavior in a nest she and her sister made in the garden , but we haven't found any in quite some time. I've constantly monitored her for egg blockage, but that's been ruled out as the issue. She appears much more lethargic than she did a few days ago, laying in dust for several hours a day, and going to bed 2-3 hours before her sister. She still free ranges in a 70ish yard diameter, but isn't nearly as active as she was a few days ago. Other possibly notable information: around the time she stopped laying, her backside was constantly covered in feces. Her vent looks normal, and feces were sometimes yellow in the past few days (she's pooped several times today though, and nothing unusual). I know this post is all over the place, but does anyone recognize these behaviors/know what's happening to her? Thank you!!
