Along with the scent openings the housing has at least a transparent portion such that when the calf is warming a mother cow can not only see her calf but additionally smell her calf to ensure the mother cow does not reject the baby calf after the warming process.

Abstract: A power control device for automatically and proportionately metering power to a heating device used to create a warm microenvironment conducive to the health and growth of an animal during a predetermined incubation period is herein disclosed. The power control device transmits proportionally more power to a heating device where an ambient temperature measured outside of the microenvironment is nearer a predetermined lower limit, and proportionately less power when the ambient room temperature measured outside of the microenvironment is nearer a predetermined upper limit.
