Or, one person's definition of permaculture.
Permaculture seems to be loosely defined as a system of agriculture in which the various aspects involved support one another to produce in a symbiotic manner that can last for a long while. I have discovered that the philosophy includes, for me, a flexible and creative mindset in which, when I encounter a problem, I don't fight the natural inclinations of the organisms I work with, but instead find solutions that go along with the nature of each critter or plant or landscape involved.
The chickens gave me such a problem over the last several weeks. Some of my Black Andalusians have been insisting on getting into the barn (even when I closed gates and doors) even if it required flying into the window, in order to lay their eggs in the manger. This caused problems at feeding times as sometimes these same hens would peck the noses of my hungry ruminants. I spent a long while chasing them out and trying to keep them in their smaller yard around their coop, but to no avail. Then my permaculture philosophy kicked in! I built them a nesting tray above the manger, with a sheet attached to cover the hay area for the animals. Even as I was putting up the side rail a chicken came in and started laying an egg!
