When electric supply is uncertain use of a standby generator is advocated. Receipt of eggs from the farm and the delivery of chicks should be away from each other to reduce infection. Persons working in the hatchery should use showers, and change clothes and shoes before entering. It is a good practice to start the incubator and the hatcher at least 24 hours before setting the eggs to maintain a constant temperature. Fumigation should preferably be done-at the end of the working day and then the rooms closed. Potassium permanganate may be placed in a glass or earthenware container and formalin poured over it. Longer Incubation Time The first difference to note between hatching duck eggs versus chicken eggs is the longer incubation time. Fumigation is usually done with formaldehyde gas using 40 ml of 40 per cent commercial formalin and 20 g of potassium permanganate for each 2♸ m3 of space inside the incubator or hatcher. Ideally, the humidity level when hatching duck eggs should only fluctuate between 55 to 65 percent. Getting the humidity levels right inside the incubator and keeping them stable is crucial for the hatching process. This reduces the incidence and spread of diseases. For best potential hatching results, the duck eggs should shift position a minimum of four times per day. They should be properly cleaned, disinfected and fumigated to kill disease organisms before storing and after transfer of eggs to the hatcher. Hatchery ManagementĪt the beginning of hatching season the incubator and hatchers should be thoroughly checked for their functioning and defects, if any, rectified. Incubators, which provide similar environment as that of broody hens, but more efficiently, are used at present for hatching of eggs. This method of hatching is highly unsatisfactory for large-scale production of baby chicks. She said she was initially trying to hatch some quail. Only 10 to 12 eggs can be put under 1 hen. Ms McDougal, who lives near Rugby in Warwickshire, said Morri was doing 'absolutely great' and she planned to incubate more eggs to hatch. Desi hens proved to be ideal for this purpose. In early days eggs were hatched by placing them under broody hens. Hatching of eggs refers to the production of baby chicks.
