No instructions on how to train chickens to use this item. Item was also too light to operate effectively when only partially full of feed as when chickens stepped on plate the unit would tip forward preventing feeder from working effectively. Works well once chickens are trained and feeder is kept full. Ideal for feeding while keeping pests like pigeons and mice from accessing feed.to train chickens I propped the lid partially open with a couple of clothes pegs till chickens learned how to step on plate to open. then gradually reduced opening once behavior was learned.
