Choose catersource eggs hatching eggs hatching Before, to select the egg mass characteristics of each breed are not too big or too small, too round or too long. Specifically Ri eggs have 41-43g volume, chicken 45-50g Gold Train, Tre 20-22g chicken, chicken 55-60g Measurement, Dong Tao chicken 52-62g, Lake 50-53g chicken, chicken Choi 50-55g , chicken Triad 50-52g. Clean egg shells, not breaking, the air chamber (at the top to egg) small, no bloodstains or foreign bodies inside. Artificial incubation is used incubators for hatching eggs. The principle of the incubator is to create heat mode, humidity and fresh air like chicken hatching case. Heat source for the incubator may be power or water vapor. An incubator incubating each incubation period 1000 results (typically 300-400 to 600-700 results) if steam hamlet or village some three thousand fruit to 10,000 villages with fruit if there is power relays automatically disconnect power. In incubators with main parts: heat and air conditioning fan, exhaust fan, humidifier water tray, egg tray and rack devices automatically turn the eggs. If using steam incubators, need frequent monitoring temperature regime, moisture to promptly handle abnormal cases happened as increasing or decreasing temperature, humidity catersource etc ... lack. Where used incubator hatching eggs, need to make the following points: a. Sterilization Disinfection with formaldehyde incubators and potassium permanganate (per 1m3 20cc machines 16,6g formaldehyde and potassium permanganate). Place medication into the disk to disk on the bottom of the cabinet for drugs evaporation, and closing vents in the back of the incubator catersource for 45 minutes. Then open the machine, fan flew off out gas formaldehyde. b. The necessary conditions during the incubation temperature is the most important event in the process of hatching. For temperatures between 37,5-37,8oC chicken. If high too chicken to be mine soon, I usually open hatch leg navel rings, sometimes birth defects. If 41-42oC extended to up to 1-2 hours embryos will die. Without heat embryos will not develop on prolonged bloom. Humidity: During incubation catersource period (1-18 days) moisture content of about 55-65% right. Hatching period (19-21 days) 80-85% catersource humidity. If in the process of hatching, chicks are too high humidity will hatch heavy abdomen, inner shell covered in slime. catersource If moisture deficiency hatched chicken feathers would not cotton, low volume. Just enough moisture to hatch chicks for about 60-61% of the eggs hatching. Ventilation: Like other creatures, chickens also need air to breathe oxygen, and carbon dioxide catersource emissions (CO2) and water vapor out. Intensity increased air exchange at the end because along with the development of the embryo, oxygen requirement (oxygen) also increased. It has been found in laboratory incubation period to 16 days of air required in every 500 eggs a day to 1m3 air, the blooming period to 4m3. In these incubators are vents. The open hole size depends on each stage incubation with the procedures specified in each machine. Egg Island: The machine automatically turn the eggs every 2 hours once. If the system does not create automatically turn the eggs, then the operator must manually island. Island catersource eggs from outside to inside, from the inside out. Benefits of Egg Island is to give to evenly distribute the eggs and avoid egg stays right place, the embryo from sticking to the shell eggs are developing, will eventually die. When the eggs were transferred to hatching stage (18 days) does not turn the eggs alone. Soi eggs: hatching eggs will hatch in 20-21 days. Usually shed 2 times. Activity 1: (7 days) to remove the dead eggs or early embryos catersource embryos. Embryonated eggs still in the shed at hatching eggs yet. Dead eggs or embryos have black blood black dots stick to the shell. Egg development is good, dark spot in the middle, surrounded by blood-ray spider development. Activity 2 (18 days) of eggs shed type embryos or embryos die too weak. Cooling: For waterfowl eggs often have more cooling process eggs, egg trays pull out 2-3 times a day. c. Choose chicken newborn chicks hatch, choose chicken type 1 is the quick, bright eyes, cotton wool, not stodgy, succulent legs, not exposed navel, ring foot, crooked beak. Chickens hatched barn taken down no later than 24 hours due to a long-in chicken diet is not difficult to keep the foot dry out. good hatching, chicks accounted for 95-97% of type 1.
