I have a year old hen who has been making a nest in the doghouse for several weeks. She goes in and sits on it for a few hours each morning, then emerges suddenly making her egg call. I've only ever found one egg there, in probably 8-10 weeks of seeing her do this daily. She is not broody, just pretending to nest and lay. Never see her in the nesting box anymore, though before this doghouse business, she laid there regularly. Do hens really fake it sometimes?
