By the 1950s, fertilised chicken eggs had become one of the most widely used model systems in embryological and developmental biology research, prized for their accessibility, transparency, and short developmental timescale. Researchers used them to trace neural development, limb formation, and hormonal signalling. The humble hen's egg thus contributed to foundational biological knowledge that underpinned twentieth-century medicine and the life sciences that increasingly informed nature poetry and ecological writing.

The use of chickens as model organisms in science since 1950 appeared in science poetry that explored life's origins and mechanisms. Poets like A.R. Ammons utilized these themes to delve into the interconnectedness of life and the scientific inquiry behind it.
