Walkswithdog, made an excellent point in regards to the smaller table top incubators. I did visit the Dickey website, and their cabinet units seem like a good investment.
My interest is in the use for chicken and duck eggs. I'd be interested in a complete unit that incubates and hatches all in one unit. I was looking at the product page and there is a complete 2X2 unit for $631. Then there is the additional accessories of a dual wafer thermostat (?), a TRH 158 hygrometer, 6 inch tray spacing, humidity systems, etc. So now I'm pretty much lost in confusion of all the technical accessories.
Perhaps someone who has this Dickey unit might be able to enlighten me on this unit as well as all the accessories. I was hoping a YouTube search would have given me a tutorial from start to finish on this product, but no such luck.
