Egg hatch assay (EHA), also called an egg hatch test (EHT), [1] is a method used to determine a given parasite's resistance to extant drug therapy. [ 2 ] [ 3 ] Fresh eggs are incubated from the parasite of interest and serial dilutions of the drug of interest are applied.
A modern egg incubator. An incubator is a device simulating avian incubation by keeping eggs warm at a particular temperature range and in the correct humidity with a turning mechanism to hatch them. The common names of the incubator in other terms include breeding / hatching machines or hatchers, setters, and egg breeding / equipment. [1]

In permanent ponds, dormant egg production increases in March, just before an annual increase in feeding activity of sunfish. [17] This example demonstrates that germ banking may take different forms within a species depending on the environmental risk presented. Bet hedging through variable egg hatching patterns are seen in other crustaceans ...
Vent sexing in Wenchang, Hainan, China (2014). Vent sexing, also known simply as venting, involves squeezing the feces out of the chick, which opens up the chick's anal vent (called a cloaca) slightly, allowing the chicken sexer to see if the chick has a small "bump", which would indicate that the chick is a male.
