My Barred Rock has been sitting in the nest at least since 11:00 am - it is now 6:00 pm. There are two eggs from other hens under her. She is being very quiet and still; when I touch her back she puffs up her feathers and once stood about half-way then sat back down. She is 10 months old, healthy, has been laying consistently and is a happy, docile hen. What's going on here? I only have a totla of 4 and they all get along well. HELP please form all you experts! I am worried about her w/out monitoring over night. It has been over 90 degrees here today and she has had no water or food.
