My top-of-the-order chicken, daffodil, has gone broody. Tonight I went to block the nesting boxes, so she couldn't access them. She was sitting outside the boxes in the broody hen posture, and the lowest chicken on the order pecked her quite hard in the face. No blood, thank goodness. Daffodil didn't do anything to her. Three more chickens did the same think, on the head and back. No feather pulling or blood drawing. Anyways, I took Daffodil out, just in case the pecking got worse. I figured out she can defend herself, she puffed up and chased a cat around the barn. I put her in the 'infirmary', a little 3'x3' cage we built for things like this. So, do you think they are picking at her because she's broody, is she sick, ect. She was 'vibrating' earlier, which I asked about also-http://www.backyardchickens.com/t/727205/why-is-my-hen-vibrating What are your thoughts?
