Sadly I candled our eggs at 14 days, and not too surprisingly found no signs of life 🙁 . So it is official our first incubator failed. Not put off, I found a styrofoam box that I had been sent something in from overseas and I decided to try and re-make the incubator and order some fresh eggs.
The first thing I did was make my own “water-wriggler” because I am cheap and impatient. It is basicly a snap-lock bag half filled with water then placed inside of another then taped into a cylinder. In the middle of the water tube I have placed the end of my cheese making thermometer. This will give me a better idea of the temperature actually inside the liquid of the egg.
Inside the incubator box I filled two pickle jars with warm water in the box that sits next to the computer fan and light bulb and under my new styrofoam box. These will act as a heat sink and help stabilize the temperature.
To let the heat and fresh air into the styrofoam box I cut two 1 inch holes on the end where the light bulb and the fan are. I also poked a 1 cm square hole on the opposite end to put the thermometer into the water tube through.
I was struggling using a 60W lamp, it was too hot so I had to have lots of holes in the box to let the heat out, so that also let all the humidity out. So in my 2.0 version I have reduced down to a 40W light bulb and taped over the holes in the outside box.
I cut a hole in the top of they styrofoam box and covered it with the front of an old CD case, and taped it down well. This gives me a window to check the temperature/humidity on my thermometer through. I have also added a glass jar of water into the top box as a second heat sink.
I have found that two sets of two sponges keeps the humidity up, and I have to cover the box at night to keep it warm enough. I ran the box for a full 48 hours to ensure I could keep the temperature and humidity stable before I added our new batch of eggs.
I poked the thermometer through to the water tube from the outside:
I have given up on our auto-turner for now, I am checking their temperature so often anyway (paranoid much?) So I may as well turn them while I am there.
Fingers crossed this 2.0 version works!
