Great start! Of course you understand that building bators is a separate and dangerous addiction ALL IT'S OWN?
Each one leaving you wondering - what if, and can I, and wouldn't THIS be better? Each leading you further down the path of the incubator tinker.
Until you plunge headlong into building, experimenting, finding old ones and rehabilitating them, each hatch yielding: "wow that worked," "this might have worked" or, "should I?" until you sit there in an evening thinking of chickens and rebuilds, and you cannot even hear or see the TV or the children for the spinning wheels in your head. ( Kind of a micro-vacation.)
It's perilous, seductive, interesting, demanding and wonderful.
I recommend it highly - said the woman on her fourth homemade and first rehab of an antique bator.
It's good to see what you build hatch something. It's satisfying to know how and why a bator works, how to improve it. To learn what YOU would do differently.
My first store bought I learned to work well but the design wasn't ME friendly. The rest is a long slide into addiction that I cherish and recommend.
