This article has three key themes: ontology (what kinds of beings there are in the world), affect (cognitive and corporeal attunements to such entities), and selfhood (relatively reflexive centers of attunement). To explore these themes, I focus on women's care for chickens among speakers of Q'eqchi' Maya living in the cloud forests of highland Guatemala. Broadly speaking, I argue that these three themes are empirically, methodologically, and theoretically inseparable. In addition, the chicken is a particularly rich site for such ethnographic research because it is simultaneously self, alter, and object for its owners. To undertake this analysis, I adopt a semiotic stance towards such themes, partly grounded in the writings of the American pragmatists Charles Sanders Peirce, William James, and George Herbert Mead, and partly grounded in recent and classic scholarship by linguists, psychologists, and anthropologists.
