Birds are born in eggs, emerging into this scary and predatory world from some of the largest single cells on the planet... So it seemed only fitting that they continue to live in this embryonic shelter and lay eggs within it themselves. Eggs, within an egg... Egg-Inception, if you will. Download and print this 'eggceptional' bird house if you like seeing plastic eggs holding other eggs and their maternal multicellular organisms within your garden.
