I just got my new Dickey incubator going. I love it. I got the model with 3 incubating trays and a hatching tray in the bottom. I debated between the 2x2 and this one, but Mr Dickey mentioned that with tray covers 13.40 Ea. any tray can also be used for hatching. I was happy to see that the thermostat was a proportional thermostat, and does a great job of keeping a steady temp. He recommends 1/3 open for the vents in the back. With the pan 2/3 full of water, humidity was 58%(perfect for hatching) so I covered the pan with aluminum foil, except for 1 1/2" in the front, and now it is at 40%, which I like for incubating fresh eggs. It has kept a steady temp of 99.5 for 30 hours so I just turned it off to wait for hatching season in February. The price was 631.75 plus 40 for tray covers and 35 for egg positioners.. I will get back in a couple months when I start hatching chicks.
