After losing 3 doz. eggs, by our count, we decided to lock our chickens up in their run with hopes they will all learn to lay in the nestboxes. Our EE is not fairing well. She paces back and forth, poking her beak out of the wire while she walks. I go in the coop to check for eggs and she comes running in waiting to catch me off guard so she can sneak out to lay her eggs. She does the egg song and I put her into a box, but she gets out and waits by the door. All the others seem to take this adjustment well. Will she get used to it? About how long should we keep them locked up?
