I hear you... I didn't intend to incubate eggs either. I got eggs for my broody duck but she wouldn't sit on them so I had to throw together an incubator. I was quickly addicted and with each hatch have upgraded... getting a bigger cooler... adding a fan... adding a thermostat... building a hatcher and now I am working (slowly) on a cabinet incubator!I thermostat is something I have certainly considered. I kind of got thrown into this incubating thing, though. A month ago I didn't think I would be hatching eggs at all. I gave my friend some eggs after her neighbors dog killed her chickens and a week later she confessed that she didn't really have the time or patience to hatch right now, so the incubator went home with me. For now I'm just testing things out to see what works and forming ideas. We'll certainly be building a much nicer and bigger incubator before spring, though, with all the niceties included.![]()
