Be sure you have your brooder all set up and warm before you go to get them.  I strongly advocate for using MHP system instead of a heat lamp.  Also, many people brood their chicks in a space that is way too small.  By the time they are 2 - 3 weeks old, they need 2 s.f. of open floor space per chick in the brooder.
