Using wood ashes for your chickens saves you money. store them (fireplace ash only, not BBQ coals, etc) and when needed, mix 2 parts ash to 1 part sand for the chickens to do their dust bathing. And guess what? It keeps mites away.
Solar powered chicken coop, light, auto open door, etc. This is cool but my not so smart chickens would get locked outside because they don't know when sunset is I guess cause they are always out when I get home at midnight.
