Synopsis
Explore how castration and careful breeding reveal the secrets of plumage in domestic fowl.
This nonfiction work presents experimental studies on how male and female birds develop their distinctive feathering. Focusing on Sebright bantams, it describes how scientists tested ideas about heredity by crossing breeds and observing changes after castration. The book explains how the appearance of feathers can shift dramatically when reproductive organs are altered, shedding light on the biology behind secondary sexual characters.
- Learn how early experiments were designed and why certain birds were chosen
