I have always planned on making an incubator out of a broken wine cooler. I'm not planning on having anymore than 8-10 clutches per year for many years, so I don't need anything big. I've been seeing new lines of these small incubators popping up with built in thermostats for $125 to $250. What I'm most worried about when building my own is proper heat throughout the incubator. What are your opinions on my options? Weigh in time v.s. money v.s quality.
