I have a dream of going off grid and I am trying to figure out a way to incubate eggs with an alternative method. Guess I need to invest in broody hens or delegate the limited solar power I will have for an incubator because I can't think of a way to regulate temps with alternative heating methods. I came up with a Compost heated brooder idea but I am still working on it. It would be large pipe going through the middle of a Compost pile where the middle would be too hot and the 2 outside ends being too cold and the chicks would move to the ideal spot... I would have the composting Agents saved up in a bag, just mix and add water and it heats up.... I want this for an emergency brooder if the power goes out on a bitter cold day.
there was a thread on here once where someone discussed building a brooder room heated with hot water pipes.
you’re pretty resourceful and handy, I bet you could figure something out.
