I can't do that, all my nephews are about 10-15 years older than me  
Rats, I hate when that happens!  
Good luck trying to convince this guy to change, you may succeed or you may be

Here's hoping he thinks about what you are telling him.
One perspective about using harmful shavings could be that often chickens don't live 'long-term' as their purposes vary and the chicken may end up in 'Freezer Camp' or on the plate before any damage can occur to their organs.
My 18 week old chickens are free range during the day but get locked up in the coop at night and they are bedded on the bagged shavings from 
TSC which are pine.  My chickens are pets and I don't plan on eating them, just their unborn children.
