There you are--young birds in a pen of older hens may be intimidated? Not welcome to investigate nest boxes? First eggs may be on the floor--and at risk for eating, so check often, if you can. Mixed age flocks are not easy for most pullets/hens, even mixed breed are not always easy. (Sometimes there are no problems, but that has not been my long time experience!--I rarely mix ages of hens/pullets.) They WILL lay when their systems adjust--it is what they do! Good luck.
