First time letting our broody set on eggs. We are on day 8!! She is up in a nest box about 18 inches off the floor. She is the last box by the wall in the picture. I am concerned about moving her before they hatch. Is it okay to put a screen over the front of the box on hatch day and then move them once they are all hatched? Or give the nest box a higher front lip so the chicks don't fall out while they are all hatching? Does the broody not get off the nest the last few days? Any advice will be appreciated. I have a dog crate and separate area for mom and chicks to go.
