So I was out in the coop/run this morning talking to the chickens and coop kittens and my banty roo made a low screeching sound. Every single chicken went completely still. It was like a big game of freeze tag in there! They stayed frozen for about a minute and were all completely silent. They stayed put until a crow started cawing and then they shook it off and went about their business. We have hawks in the area, but I didn't see one. What was that all about?
