A bit of success; the chicken coop and run is completed and is operational. The chickens all went in to their new home on Sunday evening, after the run was assembled, the perches installed and the gate hung. We'll leave them in there for at least a week before letting them free range for several hours of each day again.
There's a number of innovations I'd like to add to the basic structure. I intend to collect the water off the roof to fill the water bowls. The kids want us to build a self-refilling feeder that they saw constructed on a TV programme recently.
