Feminist Ducks!

Unbeknownst to most biologists, there exists a small, but tightly organized and militant group of female mallards in North America that has been authentically inspired by second-wave human feminists. Since inception, they've tried many methods of overthrowing the oppressive patriarchy that plagues the duck society by refusing to lay eggs, claiming that the said practice is a bourgeois remnant of the past that must be discarded. They also take issue with the bright green coloring that is only available to the mallard drake arguing discrimination on the basis of gender and color.

Yet, because they cannot exactly bear their breasts in light of, well, having feathers, they ultimately opted for an older, quieter type of girl power.  After all, behind every great drake there is a hen!
