I have been mentally designing different versions of an emergency brooder for winter if the power goes out. I thought about Solar Panels or a gas generator but I came to the conclusion that extended power outages come with disasters which means an expensive solar set up might have been destroyed and gas lines for a generator might be too long to waste time in. The only source of heat I will have a plethora of is compost. Even if I do not have enough manure to get the heat up a bag of feed will generate a lot of heat if i compost it, and I always have old feed that did not get used in time stored up. It may be nutrient deficient but it has a lot of nitrogen in it for hot composting. Maintaining a compost is easier than maintaining a fire and the heat can be more consistent with a compost. I can not use pumps utilizing water to deliver the heat to a location. I can't just bury a compartment because it would become too hot. Right now the only design that seems to work a tunnel going through the heat of a compost. this compartment would extend beyond the compost pile with plenty of venting. half too hot, half too cold leaving a middle are where they will find that sweet spot. This wouldn't be meant to be my first choice brooder, just a plan B when the power goes out in winter. I can Build this into every compost pile I start and always keep one at the ready to start a compost pile in a hurry. Any thoughts, should I go forward with this since I can probably get the materials for free? Can anyone think of a better way to use Compost Heat and create a brooder? Should I test it out even if my power doesn't go out? (make use of those cockerels I can afford to lose).
 
Trying to think of the best material to use for a brooder half in a compost pile and half out. maybe that corragated roofing material. Waterproof and a good heat exchanger. Still a long way to go with mentally designing this before I start building a structure. I am also thinking of using brick/concrete blocks for the middle section then the part completely out of the brooder will be well vented so a lot of hardware cloth.
 
Very interesting idea, especially because I was out turning my compost today and it was up to 150 degrees!

... that said, I'd still go with a solar + battery combo

take a brooder light and place the probe/temp gage right up against the light. The Temperature is going to be very high too, but the brooder its self will be about 90 to 100 degrees. Same principle. The heat source will be very high but the living space due to distance dissipating heat will not be as hot as the source. If Half the brooder is covered by Compost and half the brooder is not covered at all, one end will be too hot and one end will be too cold. However there will be a middle area where they chicks can find their comfortable balance.
