It's a home made incubator. The box is a Styrofoam box that pet stores receive tropical fish and plants in: about 15" x 15" x 10". It has a bimetal thermostat, computer fan, and 2 x 40W light bulbs. If you are comfortable re-wiring a lamp, you can make an incubator. It was a fun (for me) project. Hubby is the brains regarding anything mechanical here. If it's breathing, or growing, my brain takes over. So he did the wiring. We blew one computer fan when we got the wires crossed, otherwise, it was super easy. "Rush Lane" does a great tutorial regarding home made incubators if you're interested. I'm guessing that the difficulty you're having is related to inaccurate thermometers or too much humidity. Some folks doing the dry hatch method aren't even jacking up the humidity during lock down. They don't add any water, and let the moisture supplied by the first little wet chick provide the moisture for the subsequent chicks. I think my last hatch would have been higher if the humidity hadn't gotten so high during the end of the hatch. I also prefer to run my hatches just a bit warmer than the recommended 99.5 (for forced air) I aim for 100 - 100.5. It seems that lower temps result in mushy chicks and delayed hatching.
Did you report me???
