Does a cold room temperature affect the eggs inside the egg incubator

[djben]

My first time trying to hatch coturnix eggs. I have some eggs inside the incubator locate in my basement were the room temperature are around 45-50 degree. My question is will this affect the eggs inside the incubator. Temp. inside incubator 38.7 C and 55 % Hum.

If the incubator is holding temp properly, then no. If you happen to lose power, it will cool off faster than if they were in a warm room.

You may want to run the incubator dry or only use a small surface area container of water to lower the humidity in there. For the first 18-19 days you want the egg to lose moisture (something like 12-13% mass loss) that will grow the air cell at fat end of egg. It's this air cell that the chicks head pips into prior to it piping and zipping the shell. It needs to be large enough for the chicks first breath. With a calibrated hygrometer you'll get the right air cell size running 30% RH or there abouts. Search "salt test" if you don't know how to calibrate hygrometer. For last few days of incubation get the RH up to 70% or more.

Below is diagram to give you an idea of air cell size by days.
