A few miles from the Oakland zoo, Jolene, a Bay Area urban homesteader, has begun a tasty exchange system. In only six months, she has created a productive micro-scale chicken hatchery. On Friday, the first day of the Jewish harvest, she began to exchange the fruits of her design. In our case, that exchange entailed fresh bread for fresh eggs. From Light Brahma, Rhode Island Red, Delaware, Polish, Silkie and Silkie mixes, Leghorn and bantams varieties, Jolene is receiving eggs daily. I noticed nothing shocking or out of the ordinary, except general calm. Jolene was friendly and forthcoming with little chicken details here and there. As her chicks meandered through the grounds, weaving in and out of the kids play structure, buddha figures sat above the hen houses keeping watch.
