A second approach for keeping chickens in your garden is the deep mulch system, described in detail in Andy Lee’s book The Chicken Tractor. You can begin with part of your existing garden, or select an area in which you wish to start a garden. In either case, first clear the area, mowing it if necessary, and then put a chicken tractor on the freshly cleared area. The chicken tractor will stay in the same location for about five weeks.
Each day, add about a one-inch layer of dried hay or straw as bedding. The chickens will eat seeds that are present in the hay and use the hay as their bedding. Adding fresh hay daily provides a fresh and clean surface for them, and the bedding will gradually build up to form a thick bed of hay mixed with manure over the five week period. Since the chickens don’t have access to the soil, it is a good idea to supply them with some poultry grit.
At the end of the five-week period, move the chicken tractor and the chickens to a new location, leaving the thick bedding in place. The bedding forms what is, in effect, a well-balanced compost heap, containing a good mix of nitrogen from the manure and carbon from the dried hay or straw. After moving the chicken tractor, water the bedding. The bedding will decompose, starting from the bottom, where it contacts the soil.
This is an excellent way to build up soil fertility in your garden, as long as you aren’t in a hurry. If you are going to use this system, it’s best to start it about a year before you plan to plant, to allow the bedding plenty of time to decompose.
If you are just starting a garden, this is also an excellent way to eliminate weed or grass cover and build up soil fertility before starting a garden.
