I have a broody hen that seemed dedicated so I gave her 7 eggs two days ago. We would like to leave her to brood with the flock as that is easiest. But I am having problems keeping her on the right nest. For the week that I tested her to see if she was serious she stayed in the same nest box, so I thought she would stay there once I gave her the eggs to hatch. However since the last two days I have seen her in the wrong nest twice. I don't know how long she was off the eggs for, can't have been more then a few hours. Why would she all the sudden not want to stay on the right nest? Also how long can she be off the eggs each day before we lose them?
