My husband is picking up a few chicks for me on Friday, he has to drive 4 hours with them until they are home, what suggestions do you have as far as packing and keeping them warm, they will be only 1 day old if they hatch on Thursday, or they will be 1 week old if we have to wait until next Friday. They are Cuckoo Marans. I just want them to be warm and comfortable, I will sit by my until I hear. Thank you, and I LOVE CHICKENS!!!!!!
