Well, the title explains it all. They had been gobbling up their food, but the last 24 hours, with six of them in the brooder, none of the feed seems gone. The only thing that has changed in that time was that I laid down another layer of pine shavings. But that's not a real change, it's the same bedding they have been using. They seem alert and cheerful, but not eating, or really drinking much, either.
