My 21 week old Lavendar orpingtons and bieldefelders still aren’t laying. Is this unusual? They have their own coop and nesting boxes. However they share two covered runs with our older hens. The older hens sometimes visit the newer ones’ coop and use their nesting boxes. The younger hens are still a bit intimidated by the older hens when it comes to food but otherwise everyone gets along great! Are the littles too scared to go in to their boxes ? If so wouldn’t they just lay in the run??
