I really appreciate your posting this experience and know it must have been very difficult to do. I'm brand new to chickens and have eight week olds that we put out about two weeks ago. My husband kept insisting they would be fine, despite the cold rainy weather, but I had my doubts because they seem too young to handle harsh conditions. Because of your posting, I will be checking them even more frequently now. I'm so sorry that this happened to you and I hope it is some small consolation that you may have saved many of us from doing the same thing.
