![]() ![]() A second method is visual observation of the immature gonads by the use of an optical device, which is inserted into the intestine of the chick. Accuracy with this method requires much training and good eyesight. Structural differences exist between the male and female. ![]() This method involves visual examination of the rudimentary copulatory organ on the top wall of the vent. The most common method of sexing day-old chicks is by the Japanese or vent sexing method. General Information – " Information About Supplies of Stocks and Equipment for Small Flocks" for equipment Incubation Series - Unit 2 "Construction of a Small Incubator" for plans: Unit 3 "Incubating Chicken Eggs" for instructions on how to operate a small incubator. Where can I get plans and parts for the construction and operation of a small incubator? Incubation – "Incubating Chickens", for recommended levels of humidity for incubating eggs.ģ. The lower the wet-bulb reading the lower the percent relative humidity and vice versa. Watch the temperature until it stabilizes and take the reading. Dip the bulb in water and place it in the incubator level with the eggs. To determine this, take a thermometer that registers between 80 and 100° F and cover the bulb with a piece of cloth. The wet-bulb temperature is based on the rate of evaporation of moisture from a wet surface. How can you check relative humidity in an incubator? Goose eggs should be turned through an angle of 180 degrees.Ģ. The eggs should be turned at least three times a day. In small still-air incubators the temperature should be 100¼, 101½, 102½ and 103☏, respectively, for the 1st, 2nd, 3rd and 4th weeks of incubation. The addition of too much water during incubation will increase the number of eggs that rot in the incubator. To increase humidity the eggs should be sprinkled with lukewarm water twice weekly up to the 25th day, then discontinued until the eggs start to pip. These high humidity requirements eliminate the possibility of satisfactory results if waterfowl eggs are set in a large incubator with chicken eggs. The wet bulb reading during the incubation period should be 86 - 88° and 92☏ at hatching time. Are there any special instructions for incubating duck and goose eggs?ĭuck eggs in large, force-draft incubators should be incubated at 99 1/4 - 99½☏ and goose eggs at 99 - 99½☏. ![]()
