I am so excited today!! I made a DYI incubator for 20 eggs and everything is set up with the eggs. I have a double yolk egg from my sisters leghorn hen. The rooster is either a Barred rock or a Maran. Starting weight of the egg is 88 grams the other eggs are from her leghorn, Maran, Buff Brahma, Easter Eggers and Rhode Island Red hens.
I have 3 thermometers at different spots in the box and 2 hygrometers. The light is plugged into the thermostat I use for my brooder. I plan on rocking the entire box so I don’t have to disturb the eggs.
Good luck with your hatch with the DIY incubator. Keep us updated!
