So the wind moved 1000+ lbs of silkie pen a foot or so. Twisted some of the gates latches and fence panels out of position. This let two pens of birds out. Hawk got a hen. One of my roosters got the crap beat out of him by the big hulking rooster that doesn't back down. The rooster was hiding in a nest box and couldn't balance. He will be ok after a couple days at most. He's been inside and already looks better.
