Need advice: How to hatch chicks with no broody hens and unreliable electricity?

Hi everyone, I’m facing a real dilemma with my flock and could use some creative solutions.

I’ve been wanting to hatch some chicks from my own rooster’s bloodline to expand my flock, but I’ve hit two major roadblocks: The Hens: I currently keep Kuroiler hens. They are great for eggs, but as many of you know, they almost never go broody. I’ve searched my local area but haven't been able to find any traditional broody breeds to use as "foster mothers.

The Power Issue: I considered buying a small incubator, but my village has very unreliable electricity. The power usually runs on a "2 hours on, 2 hours off" schedule, and sometimes it’s out for even longer. Since incubators need a consistent temperature to keep the embryos alive, I’m worried a power cut would ruin the entire batch.

I’m feeling stuck because I really want to continue my rooster's lineage, but I don't have a reliable way to hatch the eggs. Does anyone know of any "old-school traditional methods or DIY hacks for hatching eggs without a broody hen or stable electricity?

Are there ways to insulated a DIY incubator to survive 2-hour power cuts, or perhaps other creative ways to induce broodiness?

Any help or advice would be greatly appreciated!
