My polish hen today decided to go in the nesting box and stay. She's been in there all afternoon and staying there instead of perching for the night with her flock. I watched her for sometime and she would make a noise , low not loud. She was also going around the box. Left then right and so on. Never leaving the box. She has not layed and has just finished molting so she isn't laying again yet. She let me look under her no problems that's why I know no eggs under there. She is also moving her feather like poofing them out and her tail feathers. When I went out there this evening she looked like she was sleeping in there too. Broody ? Polishes aren't known for going Broody but what is she doing ?
