My salmon faverolle has decided she wants to sit in her nest. all the time. She's not particularly cranky. When I push her out of the coop she runs to the food and water and practically gorges herself, and runs right back to her nest as soon as I turn my back. She's showing no signs of being sick, eyes bright and clear, feathers look good, no mites. Hubby thinks maybe she's just trying to stay warm, but I do think maybe she's broody, but this is our first time with chickens so I've never seen one broody. Her laying has slowed down, I blame the winter for that. The only change is the ducks have started sharing their coop at night, but her behaviour started before that.
