I ordered 25 eggs from an ebay seller and got 30. 2 cracked during shipping and 2 more by my own fault when I was being clumsy in transferring them to the bator cradles. Started my incubator with a salvaged Ikea drawer. It had a frosted window that I thought was perfect for viewing. Went with the water heater thermostat option. Took me forever to find it since no one at my local Home Depot seemed to know where to find it in the store. I had to order it online to pick-up in store. (inventory said they had over a dozen available!) View through window on day one. Not the smaller cpu fan in the left hand corner. It pooped out a few hours later... 1/4 hardware cloth. 1/2 in thick foam/foil insulator. Wire cradles for eggs. Luckily my rosewill challenger computer case has extra case fans. My motherboard doesn't need that MANY fans so I took the smaller fan out to use. Twice the size of my old fan, but much more quiet and efficient! My window was releasing too much heat. The eggs closes to the window were only getting 97-98 as opposed to everything else getting 99-100. Had to make an insulated flap from duct tape, cardboard from water heater thermostat package, and foam/foil insulator. Top view closed. Just a rag and 1 layer of .5 inch thick foam/foil insulator Top view open. I didn't modify my thermostat really. I drilled a bit into it on the right center side but I stopped mid way through and said "Screw it. Let's just see if it works without anymore modification". It did! Almost always 99 through out the bator. Occasionally 100 when it's reallllyyyy hot outside. I wanted to make an egg turner but I ran out of time and scrap resources. Maybe next hatch, if I choose to hatch more. It's small! I know! I plan to make 2 levels on lockdown. I saw videos of chicks just running in circles or sleeping right after hatching. I figure they don't need that much head room. So my lockdown build pics will come later for my itty bitty incubator. Humidity! It's my biggest issue. its fluctuates too much. I'm talking big difference. from about 36 to 64! We get some humidity hear now but I read some places say i should have a low of 45 and a max of 60 during incubation. A bit higher during the actual hatching. Heat Heat is almost perfect! It's 99-100 all around the cage at any time of the day. It's almost always 99 though and 100 is when its about 96-100 degrees outside the house. The lows are because I made a hardware cloth stand for it and left it out of the bator for about 10 mins. Then again when I was candling.... just easier to grab in there without knocking it over. So hopefully in 17-18 days I'll have some fluffy balls of joy to show you lol. Or possibly complete failure and a new bator.
