i am trying the third "test" run for my home made incubator. The 1st run i had humidity problems (could not keep it high enough), and hatched 1 of 12. 2nd run i had a power outage on day 18, and the temp dropped to 85, hatched 0 for 24. hopefully the 3rd will be more successful.
the brains of the operation is a hotwater thermo. the heat source is 3, 70 w light bulbs. the egg turner is a string that is tied to pvc trays. the string penetrates the top, and attaches to a hook. it should be able to hold ~150 eggs.
