I ordered 25 straight run silkie chicks a month ago from Cackle in Missouri. The weather is turning off very cold on the day they are to be shipped (Wed the 18th). ( I live in central Missouri, will they have a chance to make it in 18 degree lows and 30 highs?? Anyone have stories or experience with how this may turn out? This is my first mail order and I am very nervous about the possible loss of life. Just last week we had 70 for highs!!
