![]() ![]() However, despite the fact that percentage hatchability from locally broody hen is more efficient than from any type of incubator from a given number of fertilized set of eggs using an incubator to hatch has three basic advantages over the broody hen chicks are hatched whenever there is demand for it rather than having to wait for hens to become broody, large number of eggs can be hatched with incubator at a time, if the poultry breeder desires to sell baby chicks an incubator is absolutely necessary. The increase in demand for chickens due to population growth, which cannot be met all alone by large cabinet incubator operators, the huge cost of installation and operation of the large cabinet incubations, also the high cost of imported parts as a result of unfavourable exchange rates, discourages the installation of such large cabinet incubators by small scale farmers. Small cabinet may be considered due to the following reasons. The need for a small cabinet incubator is to generally increase hatchability of eggs which leads to the improvement and increase in the production of chicks and eggs for human consumption and the economic market. Colour of the egg does not affect hatchability, although extremely length colouring may indicate calcium deficiency in the shell. prevent hatching eggs from becoming fouled in the nest, but where this does occur, they should be scraped clean rather than washed, which is detrimental due to the fact that water may contain infectious microorganism and that washing usually opens up the pores on the eggs shell which encourages rapid evaporation.

Eggs selected should be of normal shape, a minimum of 56.7 g in weight, with good shell texture, and free from faults. If the storage temperature is too low (-2 oC) the blastoderm may freeze. The relative humidity should not be less than 80% to prevent dehydration of the eggs. The storage temperature should be about 12.5 oC at which embryonic development is arrested. Hatching eggs deteriorate with storage and should not normally be kept for longer than seven days before being set for incubation. ![]() Incubators are usually placed away from walls at corners of rooms so as to allow adequate ventilation and provide sufficient work space for the incubator operator. For small incubator about 58% relative humidity is kept at 120 oF (38 to 39 oC) up to the 18 th day of incubation after which, the humidity goes to 70% and the temperature is lowered to 96 o F (36 oC) until the chick is hatched. ![]() The heat required for incubation is usually provided by coal, oil, gas or electricity. An artificial incubator is a chamber in which temperature, humidity and ventilation are controlled for the purpose of hatching a relatively large number of eggs than a single hen can handle at a time. In natural incubation the bird provides the required conditions for the relatively few eggs she lays by sitting on the eggs intermittently until they hatch in an open space. Ncubation is the management of a fertilized egg to ensure satisfactory development of the embryo inside the fertilized egg into a normal chick, process of keeping the fertilized eggs warm in order to allow proper development of the embryo into a chick. Index Terms - development, automatic, incubator, egg incubator The result of the test revealed the following average values- fertile eggs 387, infertile eggs 29 hatched eggs 325 and hatchability of 84.06%. 420 clean, healthy, well developed and matured hatchable eggs were used to test the incubator. Turning of eggs was achieved with the use of tilting trays mechanism using an electric gear motor (0.5 h p).The trays were lifted through an angle of 40 o either side of horizontal at every hour and lasted for four minutes. Factors that were considered during the performance evaluation of the incubator were humidity, 55% and temperature, 37 oC during the first 18 days and was maintained at 37.5 oC till hatching. The incubator has the hatching capacity of 540 eggs. The aim was to produce a low cost incubator and increase the production of day old chicks for small and medium scale poultry farmers. G.Ībstract- An electric powered incubator using a forced draft principle was developed using the available local materials and it was tested with hatchable hen egg.
