Chicken tractors
The name "chicken tractor" is somewhat misleading, since no conventional motorized devices are used. A chicken tractor is little more than an open-bottom cage for chickens, which is light enough to be moved on the ground from location to another.

The chickens live in the chicken tractor and scratch, eat, and defecate on the ground surface. This process turns over the shallow surface, hence the 'tractor' reference. As the surface is sufficiently worked by the chickens, the tractor is moved to another space, repeating the process. The consumption of plants, seeds, and insects reduces plant growth and insect population, and the defecation nourishes the soil. Conventional chicken houses produce a volume of chicken waste with very high Nitrate concentration, which will burn many plants if used directly and therefore must be composted. The chicken tractor eliminates these handling and processing needs.

A chicken tractor will work on any flat surface with a substrate that supports plants and insects. Its main benefits are that it is a means of having free-range chickens and its attended benefits, but with better control/protection of the chickens. Moving it around permits more localized vegetation management, and keeps chickens out of gardens.

Visit the Greywater Portal

Planted cattails at Millcreek greywater
Greywater, sometimes also spelled as graywater, grey water or gray water, is all of the effluent water from a household, such as water discharged from lavatories (bathroom sinks), bathtubs, showers, clothes washers, and laundry trays. Greywater is not wastewater from a sink used for food preparation, or water closet (toilet) wastewater.

The water leaving our homes carries nutrients and value. It may also contain pathogens, and/or harsh chemicals and care should be taken with it. However, it is not a great risk compared to blackwater (sewage).

Redirecting the water we use for tasks such as showering allows us to reclaim some of that value to grow plants and recharge the water table. It may be necessary to choose our soaps and detergents more carefully, if we use the greywater for watering and fertilizing plants.
