Cayuga Duck Hatching eggs
How long does it take for Cayuga duck eggs to hatch?
HATCHING OF EGGS
Hatching of eggs refers to the production of baby chicks. In early days eggs were hatched by placing them under broody hens. Desi hens proved to be ideal for this purpose. Only 10 to 12 eggs can be put under 1 hen. This method of hatching is highly unsatisfactory for large-scale production of baby chicks. Incubators, which provide similar environment as that of broody hens, but more efficiently, are used at present for hatching of eggs.
Hatchery Management
At the beginning of hatching season the incubator and hatchers should be thoroughly checked for their functioning and defects, if any, rectified. They should be properly cleaned, disinfected and fumigated to kill disease organisms before storing and after transfer of eggs to the hatcher.
This reduces the incidence and spread of diseases. Fumigation is usually done with formaldehyde gas using 40 ml of 40 per cent commercial formalin and 20 g of potassium permanganate for each 2·8 m3 of space inside the incubator or hatcher.
Potassium permanganate may be placed in a glass or earthenware container and formalin poured over it. Fumigation should preferably be done-at the end of the working day and then the rooms closed. 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.
Persons working in the hatchery should use showers, and change clothes and shoes before entering. Receipt of eggs from the farm and the delivery of chicks should be away from each other to reduce infection. When electric supply is uncertain use of a standby generator is advocated.
