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]
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.
Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
This stage is known as zona hatching, and when there is sufficient dissolution the blastocyst is able to initiate the apposition stage of implantation. Lytic factors in the uterine cavity, as well as factors from the blastocyst itself are essential for the breakdown of the egg-coat. Mechanisms in the latter are indicated by the fact that the ...

As it was "incubated real well", it occurred to the zoo keepers to give them the second egg of a penguin couple, [4] a couple which previously had been unable to successfully hatch two eggs at a time. [5] Roy and Silo incubated the egg for 34 days and spent two and a half months raising the healthy young chick, a female named "Tango". [6]
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 ...
