All nest boxes in this category are made of cedar and come with a 1 1/8″ (chickadee/nuthatch) hole. Cedar helps to control mites and bacteria from entering the nest. Nest boxes are constructed with proper ventilation and drainage and have no perches which means no predators. An interior ladder is added to assist the fledglings.
Easy access for cleaning.
Limited designs also come in DIY kits-check with store.
