The relative humidity in the incubator between setting and three days prior to hatching should remain at 58-60% or 84-86 degree F., wet-bulb. Never block off all of the holes in the incubator as the chicks do still require oxygen to breathe. ����qtn���Ox�. About 10-14 days into incubation, start spraying your eggs once daily before closing the incubator lid after turning. �YL�B��b����Ț1 endobj We’ve done that here with the pink dots. The R-com Mini Egg Incubator is the smallest incubator you can buy. So if you’ve just plugged your incubator in and can’t figure out why the pump isn’t working, check to see if it’s reached 99.5. Fresher eggs will sink because they weigh more, while old eggs will float because they have much more empty space in them. The relative humidity inside the incubator controls the moisture loss inside the egg. %PDF-1.5 Happy hatching! In turn, that can dry out the membrane of any chicks who have begun to pip. 3. Chicken eggs must be held at 37.5C (99.5F) and humidity should be 50-65% during incubation and 70-75% at hatching time. It should be noted, however, that low humidity is typically less of a problem than high humidity, which we will cover next. If the lid is lifted after a chick has hatched the humidity will immediately drop which could cause other chicks to become shrink wrapped. The first is water surface area. The other way is with a Wet Bulb, and we explain both methods below. Set eggs in trays little end down big end up (air cell). 1-321-267-7009 - Fax. When you’re checking your incubator humidity, therefore, it is very important to also note the temperature. The incubation days will be our x-axis going across, and the weight will be the y-axis going up. endobj Regulate incubator temperature and humidity and let run for 2-3 days. This is a different way to measure the humidity, and it is done by checking the temperature of a thermometer with a moist cotton wick around its bulb. There are four primary factors to consider when incubating -- temperature, ventilation, turning, and humidity. °F is different from 50% humidity at 90°F. If you’ve ever incubated before (or even if you haven’t), you probably know that there are a lot of variables you need to keep track of. Conversely, moister air slows the rate of evaporation from the eggs. Our EX units come supplied with evaporating pads or blocks that can help to raise the humidity. Automatic Humidity Management The Incubation Specialists at Brinsea are here to answer your questions! I did put X’s and O’s on them and waiting to turn the eggs after 3 hours of them being in there.. If the temperature fluctuates even a small amount it can spell disaster, but humidity is more of an average variable. {����l�%�>�! Humidity is calculated by measuring the water vapor in the air. In order to increase the humidity all you need to do is put water in both channels and reduce the ventilation. It is also advisable to make notes during the incubation period if anything unusual happens. © Brinsea Products Inc. 2016. If the temperature drops or spikes, the humidity trays dry out, or you forget to turn the eggs… make a note of it on your incubation calendar. changes in humidity, CO2 level or to chilling alone. This is in almost all cases more than enough. The relative humidity of the air within an incubator should be about 60 percent. This is also true of eggs you are trying to incubate, although we don’t recommend a float test for those eggs. About 2-3 days before hatch time, raise the humidity in your incubator to 80%. All of our incubators can be calibrated, so even if the accuracy does come into question that can be fixed with a simple phone call to our service department. °F. The drier the air inside the incubator, the faster moisture will evaporate through the eggs’ shells. So what happens if you don’t have a hygrometer, or you aren’t sure if your hygrometer is accurate? I'm starting my 1st grow op and the humidity in my incubation chamber had dropped to 40%, my roommate wants to spray water in our incubation chamber(a plastic tote with very few holes)but i think that it'll cause mold, what can we do to raise humidity, were using a big plastic tote with a black trash bag wrapped around it!! During hatching the humidity should be at least 60% RH, and in order to keep the humidity stable it is recommended to keep the lid on the incubator at all times. 4 0 obj If you have been weighing your eggs then the weight loss should be right around 13-15%, and raising the humidity at the end will not significantly affect this. Small chicks are weak chicks, and weak chicks cannot always hatch on their own, and they may die just before or just after hatching.
