This product is intended for general poultry hobbyists and is not recommended for professional or commercial use or for incubating exotic birds or reptiles. Holds 41 large chicken eggs or up to 120 bantam or quail eggs when used with the Little Giant Automatic Egg Turner. Two 4 inch by 8 inch viewing windows allow for monitoring the hatching process and are great for educational purposes. Plastic mesh screen safely supports eggs during hatch period and is also dishwasher safe. The built-in digital hydrometer and moisture channels help maintain humidity, a key factor in egg health. The self-regulating control board adjusts the temperature to suit varying environments. We have hatched our own eggs for years in a basic Styrofoam incubator that we get for less than 50 at the local farm store. The LCD display with LED light shows accurate temperature and humidity readings instantly. Successful still air egg incubation requires starting with fresh, unwashed fertile eggs and monitoring the incubator for temperature and humidity through out the incubation period. Durable styrofoam retains warmth, generated by a gentle heating element controlled by a highly dependable, digital control board. The Fan Kit improves egg hatching conditions by circulating a constant flow of warm air throughout the incubator. This is critical on homemade incubators.This deluxe model includes a fully installed Circulated Air Fan Kit. Make sure that the ventilation holes are open to allow a normal exchange of air. It is difficult to provide too much oxygen, but a deficiency is possible. The best hatching results are obtained with normal atmospheric air, which usually contains 21 percent oxygen. Incubator Temperature Wet Bulb Readings Ventilation It is also possible to determine whether there is too much or too little humidity in the incubator by candling the eggs and observing the size of the air cells. As the water evaporates from the cotton it causes a cooling effect on the thermometer. Then place the tail of the wick in water. display with LED light shows accurate temperature and humidity readings instantly. To make a wet-bulb thermometer, just add a cotton wick to the end of a thermometer. This incubator sets the standard for incubating and hatching eggs. The greater the evaporation taking place, the lower the temperature reading on the wet-bulb thermometer and the larger the spread will be between the wet- and dry-bulb reading. If the wet and dry bulb read the same temperature, you would have 100 percent humidity. The wet-bulb thermometer measures the evaporative cooling event. Using a wet-bulb thermometer is a good learning experience for determining relative humidity. There will be more condensation on the glass if the room is cold, so be sure the temperature in the incubator remains steady. However, the condensation is also related to the temperature of the room where the incubator is being operated. In the latter stages of incubation (from the 19th day on), condensation on the glass indicates the presence of sufficient moisture. A good test is to add water just warm to the touch. Whenever you add water to an incubator, it should be about the same temperature as the incubator so you do not stress the eggs or the incubator. The pan should be checked regularly while the incubator is in use to be sure that there is always an adequate amount of water. The relative humidity in the incubator can also be varied by changing the size of the water pan or by putting a sponge in the pan to increase the evaporating surface. (This is especially helpful when duck or goose eggs are being hatched.)Īn 8-inch pie tin or petri dish containing water and placed under the tray of eggs should provide adequate moisture. Table 3 (Relative Humidity) will enable you to calculate relative humidity using readings from a wet-bulb thermometer and the incubator thermometer.ĭuring the hatching period, using an atomizer to spray a small amount of water into the ventilating holes may increase the humidity in the incubator. Too little moisture results in excessive evaporation, causing chicks to stick to the shell sometimes and hatch crippled at hatching time. Too much moisture in the incubator prevents normal evaporation and results in a decreased hatch, but excessive moisture is seldom a problem in small incubators. During the last 3 days (the hatching period) the relative humidity should be nearer 65-70 percent. The relative humidity of the air within an incubator for the first 18 days should be able 60 percent.
