My little Serama Bantam hen was in her run at 1 o'clock then when i got back at 6 she had gone, i suspected a predator but there were no feathers or any blood in the run. I searched for her in the nearby bushes and found some broken eggs on the floor but i couldn't see her. Is it possible she has been laying in the bushes and then returning to the run. I already have 2 hens broody in the nest box so is it possible she's made another nest? Or is it more likely she has been taken by a predator?
