 ordinary circumstances. The temperature of the hen's plumage 

 ranges from about loo degrees to 90 degrees. But the chicks 

 are not compelled to accept any one of these temperatures for 

 all time. They may seek that which is most comfortable at a

 chicks can be quickly warmed by nestling close to the bare breast 

 of the hen. Later they can seek a lower temperature within the
