Egg economics, compost ratios, and heating math for the backyard homestead.
Backyard farming runs on optimism and undercounted costs, and I say that as someone who loves it. The eggs taste better, the compost works, the firewood heats the house. But the people who stick with it past year two are the ones who did the math early and set honest expectations. Romance gets you started; arithmetic keeps you going.
Take the chickens, the gateway animal. Everyone quotes the feed cost and nobody quotes the coop, the bedding, the feeder, the losses to predators, or the months before pullets start laying. The backyard chicken calculator totals all of it and gives you the true cost per dozen. For most small flocks it lands between $4 and $8 a dozen, which is more than store eggs and less than the fancy pasture-raised ones. That is a fine deal if you value knowing your hens, and a disappointing one if you expected savings. Better to know in month one.
Compost is the opposite problem: free inputs, but the ratio matters more than people think. Too many greens and you get a slimy smelly pile; too many browns and nothing happens for a year. The compost calculator dials in the roughly 30 to 1 carbon-to-nitrogen target from whatever materials you actually have. And if you heat with wood, the firewood calculator converts your winter heating load into cords by species BTU, because a cord of oak and a cord of pine are not the same winter.
Two more for the lifestyle: the cups-to-grams converter for preserving and baking in bulk, and the SNAP farmers market finder, which matters if you ever sell surplus. Many markets accept EBT, which widens your customer base considerably.
Start small and measure everything. Four hens before forty, one compost bin before three, one winter of firewood math before the big stove upgrade. The homesteaders who are still at it in year five are the ones who let year one's honest numbers design year two, instead of scaling the romance before the arithmetic.
Typically $4 to $8 a dozen for a small flock once you count the coop, feed, bedding, equipment, and losses. Feed alone is only part of it. The chicken cost calculator totals everything over the flock's productive life so you see the honest number.
Aim for roughly 30 parts carbon (browns like leaves and cardboard) to 1 part nitrogen (greens like food scraps and grass). The calculator converts your available materials into the right mix by volume or weight.
It depends on your climate, house size, and wood species. A cold-climate home heating primarily with wood can burn 4 to 7 cords. Oak delivers roughly twice the heat per cord as pine. The firewood calculator estimates cords from your heating load and species.
