Does water on a hen make it more susceptible to predation? In this episode, we comb through the literature on olfactory camouflage, dissecting studies assessing correlations between nest survival, weather, and environmental conditions, and divulging into the complicated web of ecology dynamics. Strap on your science boots for this one, it's gonna be dense…
