It's just heartbreaking to see it. I have a friend who ordered chicks from a hatchery last month. Shipping was delayed and it was 5 days before they arrived. Only 7 out of the 25 made it. They sent a replacement order a week later and not 1 of the 25 survived. A couple of months wouldn't have made that much of a difference other then the fact that those babies would probably still be living. She finally decided to wait on the next replacement shipment until late next month. I still think that's a little too early but hopefully they'll be ok. Not to say that something cant happen even in warmer weather because it does. They just have a better chance of survival when they're not freezing. You just can't predict everything and just never know what might happen with usps. When you get your little ones safe and sound it will make it worth all the wait.
