Is the Deep Litter System Right for Your Homestead?

Learn about the advantages and disadvantages of the deep litter system and how you can manage a small flock’s manure easily and efficiently.

    “The Integral Urban House” is a comprehensive guide to achieving a completely sustainable urban lifestyle by creating a mini-ecosystem where residents grow their own fruits and vegetables, raise chickens, rabbits and fish, recycle 90 percent of their waste, solar heat their hot water and use a variety of other alternative technologies — all on a 1/8-acre city lot.

With its vision of an intimate connection between the urban habitat and ecological principles The Integral Urban House (New Catalyst Books, 2008) will inspire and empower people to act within their own communities to create places where they can live more sustainably. The following excerpt from Chapter 10, “Raising Small Stock,” explains one effective way to control chicken manure: the deep litter system. This method of manure management provides great benefits, such as rich compost, effective pest management and odor control. Keep reading to find out if you’re ready to give the deep litter system a try on your homestead. 

Manure Management

When we first started raising animals in the city, the purpose was as much to obtain nitrogen for the compost pile as it was to provide food for ourselves. In other words, fast aerobic bin composting came first. Think through ahead of time the manure-management approach you will use. Otherwise, within a short time after acquiring the animals, you will have an odor and fly problem that your neighbors may well consider to be the kind of nuisance many city ordinances were created to prohibit. In keeping with this advice, we will discuss the possible methods of manure management suitable for an urban environment before discussing the raising of the stock.

Chicken Manure: The Deep Litter System

The simplest approach with chickens is to use a deep litter system. Dan Clancy, a friend and former instructor at a local college, designed and once marketed a self-contained chicken house that incorporates such a system. This chicken house, which we used on the porch of the Berkeley Integral Urban House, is illustrated in the Image Gallery. In the deep litter system, the ground of the chicken house and, if the chickens are given access to the outdoors, the surrounding pen in which they are confined, is “seeded” with eight to twelve inches of compost, leaves, straw, grass clippings, and weeds. With this method it is essential that the chickens have access to all areas in which their manure falls. Then chickens themselves will consistently nick through this material, over and over, eating any fly larvae that develops. Their thorough scratching will expose all debris and manure to the drying action of the air so that odors will not develop. The regular addition of weeds, debris, and kitchen wastes will gradually build up on the floor, and at intervals of a half a year or so a portion can be removed and used in the garden as compost.

The advantage of the deep litter system for waste management is its simplicity. The chickens have access to a number of insects that may start to live in the material. Being able to give themselves dust-baths periodically undoubtedly helps to control external parasites such as lice, unlike chickens raised in wire cages, not having access to their litter. This system works as a management approach for kitchen as well as animal wastes. As mentioned before, chickens will eat almost anything, including meat. Instead of being stored to be used later in making a batch compost, the leftover materials from preparing, cooking, and eating meals can just be taken out to the chickens daily. With a deep litter system the uneaten leftovers from the chickens will help form the litter. Feeding scraps to chickens on wire is sometimes difficult because scraps fall through the cage, and the residue of leftovers in their feeding trough needs to be removed.

The disadvantages of this system are the loss of nitrogen, greater needs for space and climate protection, and the greater chance of cannibalism among the chickens. Let’s take these points one by one.

The constant turning and exposure to the air (and any rain or other water that may fall on the material, if there is an outdoor pen), will cause nitrogen in the manure to move into the air as ammonia or be leached down into the soil. The latter may be prevented to some degree if there is a cement floor beneath the litter, but a soggy mass, which may develop if any excess water accumulates and cannot drain away through the soil, is undesirable also. Nitrogen that is lost from the chicken pen in this way is not available to the plants in the garden.

I used this method in the 1970's and thought it was really great. The articles I read then were definitely NOT promoting an adaptation of commercial methods. At that time some studies found that chickens kept on deep litter were particularly resistant to parasite infestations. It would seem that picking through the deep litter provides a place for valuable small food organisms to grow. At that time the advice was to scatter a handful of high phosphate fertilizer through the litter every so often to encourage the growth of microorganisms. I think perhaps picking through deep litter provides good bacteria to chickens in much the same way fermented foods supply probiotics. I only did deep littering in the chicken house, not in their outdoor run, and that worked out fine. My chickens were not debeaked, and in my mind that is a completely separate issue from deep littering. This method provides an extremely healthy environment for chickens and efficiently produces high quality compost.

Clipping of the beaks if done PROPERLY is not harmful to the chicken; however it is extreemly easy to ust off too much getting the cut into the blood vessels of the beak can prove disasterous. In backyard production this extree measue is not needed as in a commercial house where a chicken is only allowed a few feet of floorspace to roam. I will also say that some backyard coups I have seen are overstocked for the amount of space the birds are allowed to have and canibalisim is a problem for some backyard producers... I use litter to fill the floor of my indoor chicken house an area 10ft wide by 30 ft long it allows me to have more time between cleanouts.. the chickens are allowed access to an outdoor area 16x32 and most sunny days they are in the yard eating grass and kitchen scraps along with the scratch feed in the afternoon.. Using litter (SAWDUST, Spoiled hay and straw some grass clippings etc) I am able to do clean outs once per month instead of every day.. but even using this system you have "Trouble spots" areas where litter gets wet etc..the key is keeping it dry as possible to avoid problems in the feet... Common Sense is the key.. move your outdoor coup often will keep manure from building up in one spot and keep smell issues at bay. You can collect the manure and add it to compost or use your coup like a chicken tractor over small sections of the garden too... The problem there is no one system that will work for everyone.. pick and choose a system that works best for you.. if neighbors are not complaining you are doing a good job believe me if you leave that coup in one spot forever and do not have a way to handle your manure etc when the ground gets soaked you are only asking for problems...

I hope new urban chicken owners do not follow this really really poor advice. I was appalled to read this.
