I received my order of 25 chicks (+ 2 free ones) yesterday morning with no losses. I was notified on Sunday by McMurray that they were shipping and the post office called me on Monday at 8 am before they even opened. I live in western NC. My chicks are doing beautifully. I wouldn't hesitate to use McMurray again. Mail order, particularly in cold months, may not be a good choice for you because of your postal service. You probably have some good local hatcheries in your region. Your county extension agent may be able to tell you where to go.
I am very sorry for all those who have the disappointment of receiving a shipment of dead chicks. I certainly had that fear since these were my first chicks and fully expected some losses.
