Lol. I don't think Hatch-A-Holics would work, it would just become a huge swap for hatching eggs... lol.
I tried the homemade route as well, but I didn't want to spend more on a thermostat wafer than I would on a whole incubator, so ended up going with a dimmer and fried the eggs that had developed. I thought about making an incubator with a nice computer thermostat, but, after weighing the costs, it would have been about the same to buy a 1588 w/ the autoturner. I ended up going with the pre-made one, because, well, if I had spent $200 or so MAKING an incubator, I would have made a monster of an incubator, then later would have been tempted to fill it, and then would have ended up in a bad situation, lol. As it is now, I'm buying, incubating and scheduling eggs that I have no room for. I bought two dozen chicken eggs, and I only plan on keeping 3 chickens (and I already have two chicks here!) I have the feeling that I'm going to end up with more chickens than I originally wanted to, but, hey, at least I'll have the choice of white, brown or blue eggs each day for breakfast! Lmao.
Let us see pics of the homemade bator when you're done, and we want to see it FULL of eggs, no skimping, or you'll get a D+ for the day!
