Proper management is critical for successful hatchability. Inadequate breeder nutrition, mating problems, improper egg handling, incubator or hatcher malfunctions, and humidity or temperature problems can cause hatchability problems.

Successful management of a moderate size hatchery requires a high degree of expertise and attention to detail. Cleanliness is very important. The environmentally controlled hatchery building should be designed for durability and ease of cleaning. It should be of sufficient size to handle anticipated egg volume and must include areas for egg cleaning and culling, egg trays, cooling and storage, incubation and hatching, chick holding, equipment washing, and storage, as well as office and sanitary facilities.

Equipment requirements for the hatchery include a standby generator, forced draft incubators and hatchers, service tables, a vacuum for cleaning, pressure washer, tray washers, and carts. Incubators and hatchers that can be used for emu eggs are manufactured and sold by several commercial companies.

A good ventilation system is a must for successful incubation and hatching. In addition, when building a hatchery, keep in mind that emu eggs require a low relative humidity (24 to 35 percent). Thus, in areas of the state with high relative humidity during the emu's breeding season, a dehumidifier system should be installed.

Incubation Requirements                                                                       

Emu eggs should be stored with the large end up at a room temperature of 40oF to 50oF. During holding time, the egg should be rotated twice a day. Better hatchability may occur if eggs are set (placed in the incubator) within 2 to 4 days after lay. Longer storage may reduce hatchability.

Never set an excessively dirty egg. Manure or dirt should be gently scraped off. It is generally not advisable to wash eggs unless absolutely necessary.

Incubation time to hatch for emu chicks is between 48 and 52 days with about 50 days being the average. The optimum incubation conditions for the emu are in the range of 96oF to 98.5oF dry bulb temperature with a relative humidity in the 24 to 35 percent. All bird eggs lose weight during the incubation period.
