And theyâre not as expensive as youâd think: GoToMeetingâs costliest plan, which supports up to 100 users, costs $49 per month, and thereâs a free version for small teams. Even at $49 per month, youâre looking at less than $600 per year â likely lower than the per-employee cost of a single business trip.
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. When hatching, the humidity is increased to 65% relative humidity or more.An excellent method to determine correct humidity is to candle the eggs at various stages of incubation. The normal size of the air cell after 7, 14, and 18 days of incubation for a chicken egg is shown.or still-air incubators, add 2-3 degrees F. 2 Measured as degrees F. using a wet-bulb thermometer. Use chart to convert to relative humidity. Sanitation In large commercial incubators, eggs of different ages are often set and each setting transferred to a separate unit prior to hatching.
1 If the incubator is not already in operation, start the incubator and allow the temperature and humidity to stabilize a day or two before setting eggs. 2  Set the temperature at 37.5Â°C (99.5Â°F) and relative humidity at 55% (84.5Â°F on wet bulb thermometer). 3  Set ventilation as recommended by the incubator manufacturer. As the hatch nears completion gradually lower the temperature and humidity so that by the end of the hatch the temperature is at 36.1Â°C (97Â°F), and the humidity is at 70% (90Â°F wet bulb). 2  Vents should be opened to their maximum setting by the end of the hatch.
