The Duplex Bird Feeder Kit contains materials for kids to build a place for birds to gather and eat. It can make for a fun scout group activity or an entertaining project for school or family time. It includes wooden parts with pre-drilled holes as well as nails. Once completed, it can be finished for a shiny look or hung as is and filled with bird feed. This unfinished birdhouse for kids is recommended for ages 8 and up.
