I have almost everything ready. My first shipment of chicks are shipping out from cackle hatchery on the 10th (Monday) of this month. I have Wednesday off in case they come that day and if they come a different day, I have someone who will pick them up while I'm at work. They're 25 st. run bantam silkies. They're shipping to my local post office here in Michigan. I only live about 10 minutes from the post office so they don't have a long journey once they arrive here. Other than having my brooder heated up, (it's outdoors but well built and insulated) what else should I do to make sure they are happy and comfy when they arrive?
