Smoothed carbon dioxide concentrations measured among sensors across experimental days. The average pattern of CO2 sensing showed a gradual rise in CO2 concentrations, likely driven by bringing the animal into the barn at the start of sampling. Thereafter, there is considerable natural noise within the data reflecting the various potential CO2 sources in the environment
