Built this one when I had an overflow of eggs that wouldn't fit in the one I built first.
We had a cooler lying around that we'd used to keep food cold during a week without power following an ice storm last winter.
Bedside clip-type lamp hubby didn't need for a month or so (he probably begs to differ, I just decided he didn't need it) and he now has back since we're done incubating!
Foil from the kitchen
Left over shelf liner
Old jelly jar
2 sponges 33 cents each
Plastic from $1 picture frame I'd used in building another incubator
Caulk from hubby's tool box
I traced a hole on the lid of the cooler around the metal light shade. Cut the hole out with a steak knife. Lined it with aluminum foil to seal air leaks and keep the hot light from touching the styrofoam cooler. (This light has is in a ceramic fixture and has a metal shade, so nice and safe.)
Cut a rectangular hole in the front of the cooler, squeezed a line of caulk around it on the inside of the bator, and sealed on the piece of clear plastic for a viewing window. I let that dry for a few hours.
Lined the bottom and sides with aluminum foil, then put the shelf liner in. (Okay, I put the shelf liner in after the babies started hatching and were slipping because I forgot to put it in!)
Filled the jelly jar with hot water, put the sponge half in and half out. Put it in a corner of the bator.
Poked air holes all around with a pencil. Taped them closed when needed.
Put the eggs in, set an old temp/humidity gauge in on top of them, kept it around 101, voila! I used a 25 watt light bulb in the lamp, I think, though could have been 15 watts. I did switch the temp/humidity thing back and forth with the other bator and put the little $1 thermometer in this one sometimes as I only had one humidity thing and two bators!
I hatched out ten quail, three chicks, and two ducks in this bator, all in the same incubation. Quail hatched a week before the chicks, and the ducks a week after the ducks. All still healthy, happy, and strong, growing fast!
They're 2 months old now.
We had two, several hours long, power outages during incubation, and still hatched 10 of 18 quail eggs, 3 of 4 chicken eggs, and both duck eggs. My pics show more eggs in, but one of the three duck eggs wasn't fertile, and I moved some of the chicken eggs into the other bator, so ended with four chicken eggs in it.

I would sooo love to hatch some cochins! We bought a couple of cochin chicks with our guinea keets last summer, but they only survived less than a week. They ate and drank fine, just never grew or started to feather out, and just didn't make it. My kids were heartbroken, as they were their special little chicks, meant to be pet chickens for them. In spite of now having RIR/White rock mix chickens, ducklings, quail, easter egger chicks, and now silkies, (all raised from chicks) they both keep begging for cochins!
