I was in a fix a few weeks back. I needed an egg candler pretty bad, but I had no idea where to go locally to buy one. I spent a few hours online and came up with this... It works great!
All you need to make your own egg candler is some sort of light ie: my quilting Ott Lite, a piece of cardboard, scissors to cut the cardboard with, a marker, some blue painter's tape, and eggs you think are fertile too, of course..
1. Using a marking pen, measure and draw the circumference of your light's shield on the cardboard. Mine was a 10 inch circle. Cut it out. Then, draw an oval in the center of your circle to lay your egg into. You'll want it to be a little smaller than your eggs so you can hold the eggs over the hole without letting light escape on the sides blinding you. My hubby says that adding a small piece of foam weatherstripping around the perimeter of your oval would be a good idea because it can hide any gaps or uneven cuts. Though I haven't done that yet.
2. Tape the circle onto your light.
Voila! you have a quick DIY egg candler.
Please note- With the cardboard egg candling mask covering the light, it's not a good idea to leave this light on for more than a minute or two at a a time, as this can lead to fire; and it should never be left turned on and unattended. I turn mine on to look at an egg, and turn it off in between eggs. I do not let it get warm to the touch. When I'm done candling eggs I simply remove the cardboard and painter's tape and my Ott light is ready for sewing action.
