Temperature is important, and so is humidity, when incubating eggs. On the Local Food Report, Elspeth Hay speaks with Susan Knieriem of Miss Scarlett's Blue Ribbon Farm in Yarmouthport about raising chickens from egg to bird. Susan does it using an old-fashioned incubator—it looks like an old wooden icebox, and it holds about 100 eggs. She collects the fertile ones—which is most of them since she's got roosters—and dates them and lays them on the trays. After 21 days: peep. Peep. PEEP. PEEP! Babies.
