So far I've only let my hens lay on my eggs, but I'm wanting to try to hatch them myself with better hatch rates. I've done tons of research on here about incubating so I know a lot. The only problem I'm having is actually constructing the incubator. I'm not quite ready to invest in an incubator as the chicks will be part of my personal flock and not for sale so I may not be using more than a few times. Can any one give advice and/or instructions on how they made their own successful incubator? I'm trying to spend as little as possible as well just in case I have no success.
