Chickens play a vital role in sustainable agriculture. They are excellent foragers and can help control pests by feeding on insects, grubs, and weeds. This reduces the need for chemical pesticides, promoting a healthier and more balanced ecosystem. Chickens also contribute to soil fertility through their droppings, which are rich in nitrogen - an essential nutrient for plant growth. This natural fertilizer improves soil quality and reduces the need for synthetic fertilizers, further enhancing the sustainability of farming practices. Furthermore, chickens can help to reduce food waste by consuming kitchen scraps, turning them into valuable eggs and meat. The integration of chickens into a sustainable farming system can therefore contribute to environmental conservation, improved soil health, and reduced waste.
