The chickens are staging protest marches, lining up along the side of the pen facing the house and stomping back and forth. If they could carry signs, they'd say, "Freedom to forage!" and "We demand scratching rights!"
They've been in lockdown since Darwin, the older Airedale, developed expensive stomach trouble that appears to be aggravated by consumption of fresh chicken ca ca after the hens have been loose in the yard. This may last until the rainy season and I fear the hens will go on strike.
