If you’re looking for the ultimate frugal hack to keep your chickens warm this winter, look no further than the floor beneath their feet. The Deep Litter Method (DLM) is a traditional homesteading practice that turns coop waste into a natural heat source and premium garden fertilizer.

At The Frugal Coop, we love this method because it saves you two things: money on bedding and time spent shoveling.


What Exactly is the Deep Litter Method?

Instead of cleaning out your coop floor every week, you manage a thick layer of bedding (about 8–12 inches) and let it decompose right inside the coop. As the chicken manure and carbon-rich bedding (like wood shavings) mix, they begin to compost. This process releases natural microbial heat, which can keep the coop several degrees warmer than the outside air.


Step-by-Step: Setting Up Your Deep Litter System

1. Start with a Clean Base

If you’re starting mid-winter, give the floor one last scrape. Sprinkle a layer of diatomaceous earth or a coop deodorizer to manage any initial moisture.

2. Choose Your Carbon (The Bedding)

The best bedding for the deep litter method is pine shavings or hemp bedding. Avoid straw if possible, as it is hollow and can trap moisture, leading to mold or “caking.”

  • Frugal Tip: Buy “Fine” or “Medium” flakes—they break down faster than large flakes.

3. The 6-Inch Rule

Start with at least 4 to 6 inches of fresh bedding. As the chickens poop, the manure provides the nitrogen needed for the composting process.

4. “Toss” the Bedding

This is the most important step! To keep the litter aerobic (smell-free), it needs oxygen. If your chickens aren’t scratching it enough, use a pitchfork to turn the bedding once or twice a week.

  • The Lazy Hack: Scatter a handful of cracked corn or scratch grains on the floor. Your chickens will do the “tilling” for you as they hunt for treats!

5. Add “Browns” Regularly

Whenever the floor starts to look a bit “messy” or you notice a faint smell, add a fresh 1-2 inch layer of shavings on top. By the end of winter, your litter should be about 10-12 inches deep.


Top 3 Rules for Deep Litter Success

Rule Why it Matters
No Ammonia Smell If you smell ammonia, your coop is too wet or lacks ventilation. Add more dry shavings immediately.
Keep it Dry This is why a leak-proof waterer is vital. A spilled 5-gallon bucket will ruin your deep litter and create a frozen mess.
Ventilation is King Since the litter creates heat and moisture, you must have open vents near the roof to let the damp air out.

 

🛠️ The Frugal Coop Recommended Setup

To make the Deep Litter Method work, you must prevent water spills. A soggy coop floor won’t compost; it will just grow mold.

We highly recommend pairing this method with a nipple-style watering system or a Heated Bucket Wrap to ensure no water is wasted or spilled onto your “heater” floor.
