Such a strange thing happened. We had let the chickens out into the garden and they'd all been happily rootling round, having their usual good time. Fizz, as normal, had yelled out "CROW!!!!" at the top of his voice whenever any kind of bird flew across his line of sight. He'd even proved what a brave little bantam he was by chasing off a Jackdaw that had had the nerve to land in the garden and eye up the bowl of mixed corn we'd placed there for the flock to snack on.
Then one of the girls, we're not sure which one, gave a low "hum". Every single chicken froze. They all stayed stock still for absolutely ages.
I'd seen a sparrowhawk hunting a few fields away earlier in the day, and wondered if it had returned, even though I couldn't see it now. They certainly didn't react this way when one of the cats strolled by.
Just as suddenly, it was business as usual. Titian resumed her gossipy prattle, Tu-Tu chased Rebecca and Punk, Fizz reminded everyone there were snacks to be had, Pom-Pom continued to ignore him and Irene went back to trying to escape into the vegetable section of the garden.
