I am a backyard chicken 'newbie'. We bought 3 young buff orpingtons about 2 1/2 months ago. They started laying within days and since then have been getting 3 eggs/day in the same nesting box. (They have 3 to choose from) One hen lays early in the morning and two lay together in the same box later. All laying is done by 9:30-10:00am. We let them out 2-3 times a day to free-range in the backyard and veggie garden. They have gotten very fat and happy! However, within the last week, one hen, Charlotte, has been 'hogging' the nesting box and pecks at the others if they want in. She'll sit in there for HOURS, while the others are pacing to get out and lay. I eventually will let them out so the other two can lay under the honeysuckle brush in a make-shift nest they've made (that we discovered after occasionally finding only 1-2 eggs in the nesting box). They flat out run to that nest and lay within minutes! Poor girls! All the while, Charlotte sits in the nesting box and, now, is not laying until late in the afternoon. What's going on? She won't come out of the coop or hang with the other girls. Nothing appears physically wrong with her. Why wouldn't the other hens just use the other nesting boxes? Should we break down the dividers and make one community box? Why is Charlotte being such a bully?
