term used by apiculturalists to describe eggs that fail to hatch, larvae that fail to pupate, and pupae and adult honey bees (Hymenoptera: Apidae), that die without infection but rather the result of genetic anomalies (Steinhaus and Martignoni).
An egg that has become rotten or the living contents of which have died or been destroyed. Purple Martins commonly roll their addled eggs out of their nest cups into the nest periphery, or out onto the porches of their houses.
