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.
