I have two great baby ducks, one is a rouen named Virgil and the other is a Pekin named Daisey.  They are a week old.  I hatched the Rouen and purchased the Pekin (for a buddy for Virgil) from a local breeder.  My question is this:  my local breeder told me to use large pine wood chips for bedding.  I know not to use cedar chips.  They are eating the pine chips, is that bad for them?  Should I somehow prevent them to eating it and how?  Thanks for all your help in advance.
