A neighbor stopped by yesterday (he has chickens too) and told me that my hens won't make it through their third winter. We live in Michigan and my girl's are 20 weeks old. He kills his in the fall before their third winter. He said that they will be too old to tolerate the cold weather and that I will find them dead in the coop as they will freeze to death. Is this true? Please say no my heart will break if it is.
