My chicken Quinn, is about 12 weeks and hasn’t started laying. She stays in the coop alone all day and just roosts in the same spot. I picked her up and set her outside with the others but she just went to the planter and roosts on the edge. She doesn’t eat as much as she did and she doesn’t move other than a couple inches. It’s not a bully problem and her sister comes to roost next to her for a few minutes. Do you know what it could be? Is it a disease or depression maybe. All the chickens were staying in the coop this week except for today when they all, except for Quinn, started to come out. It’s been windy and rained for a little bit, the temperatures have dropped about 20 degrees the past couple days. Is it a weather behavior?
