How is this as a homemade incubator ?

Np
I started with 12 eggs, 9 ended up hatching. It probably would’ve been 10 or 11 but one had a blood ring after several days and another somehow cracked while in the incubator after a few days.
I kept all chicks for the first 2 weeks, then gave all but 2 away, back to the farmer I bought the eggs from, then once the final two were 6 weeks old I gave those away as well.

Wow! That's as good a hatch rate as many people get with purchased incubators.

Good work, building a homemade incubator (and then a second one at the end) that worked so well!
