 We can't go into the chicken shed itself, but we head into a side room with a big viewing window. So this is the viewing gallery. Look! They're tiny, fluffy little yellow chicks, 44,000 of them. It's quite a spectacle, isn't it? As we approach the glass, there's this extraordinary ripple of movement through the flock. It's like a Mexican wave of tiny, fluffy ping-pong balls. It's quite a sight.
