My chicken has been laying flat off and on in the yard lately. She’s not laying in the nesting box on eggs all day, she lays her normal egg every day to every other day, and leaves the nesting box after, but she’s been laying flat a lot throughout the day in the yard. Is this a broody sign? This is a pretty new behavior for her. I’ve never had a broody hen, these are my first chickens and they’re a year and a couple months old now.
