Our PO here you need to show ID ... Once a friend couln't make it the plan was for me to go with her ID & note, last minute she was able to go so that was something we never tried.
Reason the box the chicks are shipped it is "stuffed" is to keep the warm (body heat) and from too much slouching around. But I do agree it is "tight" and some do get trampled ... LF chicks should NOT be shipped with bantams, size difference ... IMO
Where are you located?
When the TSC here (Big Island/HI) gets chicks in, they are in those metal water trough in a fenced in area that only a the person in charge of the chicks goes in when someone purchases ... Been this way for years & it's a good idea for safety but never thought of theft...
