Ooo! I would be afraid to put any of my chicks outside when they are that small. I would be like ringing a dinner bell for the Crows and Magpies! I am beginning to learn that Magpies are quite the little preditor and they work together in small flocks. I watched them one day form a "military line" and walk across my field in perfect formation herding grasshoppers. Once they got the grasshoppers cornered, they had a feast. Now the Magpies have figured out how to get into my hen house and they are breaking open eggs. They are becoming quite a nusience.
