Chris, I turned down a 300-400 egg, redwood incubator a month or two back. I simply don't have a need for that level of instant production. LOL.
I'm probably one of the few guys who remember taking eggs to "guy", often a Mennonite gentleman, who'd incubate your eggs for you in a Kerosene fired incubator. When they hatched, you went back and picked them up and paid him a dime or 20 cents an egg for his effort. There are still a few places left in the US where this is still done, but not many.
Redwood incubators are the best IMO.
Yup..people did "custom hatching" in the old days......so much an egg.
