I totally agree with TXmom. Think of it this way, mama hen doesn't keep them under her wings all the time for eight weeks or more. It's like little cimarron said, she's not on them constantly.
I started taking my two week old chicks outside in April. At first watching them constantly for chilling and danger. They got less and less supervision as they got older. By 5 1/2 weeks (late May) they were living outside without a heat lamp.
