12/14/2023 0 Comments Temperature for hatching chicken eggs![]() Early embryonic mortality increased at low temperatures (36.5✬). There was no difference among incubation temperatures in absolute and relative hatchling weights. Water loss was lower in eggs incubated at low temperatures as compared to high temperatures. Incubation length and temperature were inversely proportional. The highest hatching percentage was obtained between 35.5 and 36.5✬. Jaboticabal, SP aim of this study was to determine the effects of incubation temperature (34.5 35.5 36.5 37.5 and 38.5✬), on incubation period, embryonic mortality, hatching rate, water loss and chick weight at hatch, using daily incubation of partridge (Rhynchotus rufescens) eggs.

If yours is a manual incubator they need to turn 180 degrees each time. Most new incubators do this automatically but ensure all eggs turn. Turning your Eggsĭuring the standard period of 21 days incubation, your eggs will need to be turned a minimum of twice a day, 3 is better or more. If the humidity is too low add another pan of water and alternatively if it is too high reduce the size of the water container in the incubator. Keep in mind too that the depth of water has no bearing on humidity it is the surface area of water exposed to air. Temperature inaccuracy will definitely cause problems during hatching. Humidity does not need to be as accurate as temperature but a bad combination of both will definitely cause problems. ![]() Humidity should be 40-50% during incubation and 50-65% during the last 3 days. As you continue hatching if you keep solid notes of what you have done you should receive better results each time. If the eggs are hatching late the temperature needs to be raised and if they hatch early it needs to be lowered. Gauge your hatch results and raise or lower the temperature accordingly. Most new incubators have accurate temperature controls, often with digital displays. Having an accurate thermometer is very important. In a fan forced incubator it should be 37.5 degrees measured anywhere in the incubator. In a still air incubator, 38.5 degrees measured at the top of the eggs is perfect. The temperature of an incubator changes constantly but the temperature inside the egg will be an average of the temperature swing in the incubator. Remember that is internal temperature of the egg, not the incubator. If eggs reach an internal temperature of 105 degrees they will be ruined. It is too easy to ruin good eggs by not having your incubator adjusted properly. You should run your incubator for at least 24 hours prior to iron out any problems. ![]() Having your incubator checked and running correctly before incubating commences is important. When storing eggs for hatching you should always store them pointy end down. This way the eggs can reach ambient temperature. When you collect or have eggs posted out it is important to let your eggs settle for 24 hours, ideally next to your incubator. ![]()
