chickens harvesting their own feed





An interesting article full of observations, comments and ideas.........



chickens harvesting their own feed

Ahhhh ..... I think this is where permaculture really shines.
Imagine an area for the chickens which has en enormous mulberry tree dropping fruit throughout june, july and august. There is a plethora of clover, alfalfa, grains, sunflowers, buckwheat, peas and lentils in the more open areas. Fruit and nut trees are surrounded by siberian pea shrubs, chickweed, comfrey, dandelion, amaranth, nettles and sunchokes. Maybe some raspberries and blueberries are in the mix too. Assuming it is summer, why would a chicken eat dried up "chicken feed" with this bounty at hand?
When raising chickens on a large scale, you generally raise your meat birds only in the summer. And you harvest your non productive layers in the fall. So most of your chicken feeding efforts are focused in the warmer months when your chicken feed crops can be producing prolifically.
What, specifically, to grow depends on a lot of factors. How much room do you have; how cold does it get; what is your soil like; how much does it rain ....
Some plants produce more food per acre per year than other plants. And some produce food for a just a week and others produce food for six months. The best producers appear to be mulberry trees (lots of fruit dropped constantly over three months) and wheat (when grown with the bonfils method). Sepp Holzer pushes a perennial rye and sunchokes as the core chicken/pig feeds.
I advocate using the chicken paddock method. And along with that, I think that the lion's share of the people food should be grown in those same paddocks. A lot of the stuff we eat is great chicken food! And the chickens clean up anything we drop and anything we leave behind. Less waste.
This is a good time to mention polyculture. All plant eating animals are designed to eat plants from a polyculture. They eat plants, not from rows and rows of the same thing, but from a mix of a dozen or more species. Every plant has special nutrient needs and every plant exudes an excess of nutrients that it mysteriously has superpowers to find/build/whatever. The mycelium in the soil has no leaves and depends on developing a bartering relationship with plants to get sugar. The mycelium offers nutrients. The sugar water from a carrot is loaded with nutrients that the carrot has in excess. The sugar water from an oak tree is loaded with something completely different. The carrot gets a bit of the oak excess and the oak gets a bit of the carrot excess. Because the oak's roots cover a bigger territory, it gets far more diversity than the carrot. And the oak ends up inadvertantly sharing some of that with the carrot.
We have barely scratched the surface of what we know for human nutrition. And we have studied human nutrition ten thousand times more than chicken nutrition. Human nutrition is based on humans eating from a polyculture and eating the meat of animals that consumed from a polyculture. Rather than prending that we know all there is to know and growing things in a harshly organized fashion, I suggest that, instead, we grow things in a diverse polyculture of 50 or more species. I suspect that by doing this, the vegetation will become far richer in nutrients (both known and currently unknown) than if we attempt to infuse the soil with known nutrients. Diversity would include things that make for good chicken feed and things that make for good people feed. Rather than have an area for the chickens and an area for the people food, have one area for both (and many other purposes too).
Since paddock shift systems tend to encourage five times more growth of vegetation, the result should be MORE people food than if chickens were not rotated through the area.
For the winter, a lot of remaining grains and seeds will still be on their stalks. The taller stalks will eventually fall to the level chickens can get it. Winter apples will often stay on the trees deep into the winter. When they fall, they will keep for a long time on the ground. Kale can provide some winter greens. If chickens follow pigs in a rotation, pigs will often pull up sunchokes (and other tubers) and leave scraps for the chickens. Sepp Holzer has observed chickens eating the manures of other animals in winter. His son reports that they will provide feed to chickens only on the dozen coldest days of the year.
