My above box is a meat packing box it is a 18'' square it is card board lined with foam with a 15 w bulb room temp should be consistantly 70, do not put in sun. I have a thermometer, but don't measure humidity, never have I dry hatch, I just have a small water dish, then at first pip I add a sponge.
The pics below are a diff size box but it will help show how it is made...leave heat shield on line botom of box with foil
suspend wire over lamp, but not resting on lamp, my box wire is about 7 in. from floor of box, do not place eggs directly over lamp and eggs should not touch walls of incubator.
I also put a baby quilt in over wire. nothing at this point touches lamp- I have hatched over 100 chicks and a 15w bulb doesn't get too hot so if you are not relaxed about it at this point relax.
I hand turn lifting only the little pink lined window to keep in heat, and have a small water dish with copper penny in incubator.I test incubator for a couple of day, before putting in eggs, ( that is not true because I have tested this incubator out so many times but until you get your temp right test it.) if it is too cold I wrap with towel and keep an eye on it so it doesn't get too hot.
pretty much it,
these were hatched in the meat box from the above eggs
Next came these from the meat box...these eggs are the above chicks
These were not from the meat box, but the below are the chicks from the above eggs the box was an incubator I sent a gal in FL after hatching these chicks.
I had currently fired up this incubator again because the hen was sitting on 5 eggs and one was not fertile, so I gave her 2 more eggs (she is small) and currently I have 11 eggs in incubator. 8 have embryos, 3 went in today.
