Yesterday i went out in the morning and one of my hens was acting completely normal. But by afternoon she was spending a long time in one of the nesting boxes and when she finally left it she was much slower and not as active as she usually is. There was no egg from her in the box. She just keeps acting more lethargic and she is one of my most active birds! This morning i found some bloody stool in the coop that i believe is from her and she is missing a lot of the feathers by her vent and lower belly. What's wrong? Could she be egg bound? Please help!
