im in the process of building a rather large one at the minute and the costs of making a fully automatic one compared to buying one are 1/10th at least , its really not that hard in theory. it took me a while to source a fridge big enouh to take egg turners. im buying a few parts now and then and will soon be putting it all together.

I made a 18 chicken egg incubator from old styrofoam box, water tray and bulb for about E30

You can certainly build one for a fraction of the price. I built one over the lockdown. But haven't used it yet as I was waiting for a motor to arrive for the automatic egg turner.

With regard to building one. There is a lot of information out there particularly about temperature control. I used a W1209 thermostatic controller which only cost about €4 - fantastic device. I used 2 incandescent light bulbs (In case 1 failed)for the heat source.

I'm running some tests at the moment and the results I'm finding are interesting. There are 2 parameters that are critical to control: Temperature (Easy - see above) and RH - Easy for first stage of incubation (Before lockdown) but it's not easy to achieve the higher RH level needed for lockdown.

I'm finding that I can only achieve about 50% RH with the bottom of the incubator covered in water. From the research that I've done my understanding is that while home made incubators will work there is a chance that the mortality rate will be higher than it possibly could have been over the last few days due to the lower RH - unless you do something to rectify this. This flaw of home made incubators that I have found isn't discussed anywhere that I have seen.

I assume commercially designed incubators have a heating element installed to provide some steam, but designed in such a way as to not over heat the air.

I have an old baby bottle steam sterilizer in my garage, I'm going to try this in the airflow path into the incubator. I should be able to get this to work by experimenting with a vent size and a timer on the sterilizer to bring up the RH for the lockdown stage. By placing a tube from the sterilizer to a hole just behind the fan in the Incubator it should draw in moisturized air from the sterilizer.
