phenix.pdbtools model.pdb --show-adp-statistics

will show you more detailed (in some sense) ADP statistics. However, it 
will not distinguish chains, etc.

If you want this statistics available per selected atoms (like chains), 
then it will take two steps:

1) Make a PDB file with atoms in question:

phenix.pdbtools model.pdb keep="chain A and resseq 1:100"

2) Compute B-factor statistics for the new file obtained at step "1":

phenix.pdbtools model_new.pdb --show-adp-statistics

I will add more functionality to phenix.pdbtools so in future it will do 
it all in one go.

Pavel.
