The OP has been online a number of times since this thread developed, but, I get a feeling she will not be responding to it, even if she is reading it.
From her history of posting, the nearest feed store is 45 minutes away; from that same research, it suggests that she is a minor and dependent on being driven that milage (or, harnessing an online delivery of feed).
It is somewhat confusing because when her duckling was just a few weeks old, she was given advice on duck "treats" and even thanked a member because she had printed off a manual of treats to keep her duckling happy
yet still felt a need to post a thread asking for advice (which she clearly ignorned) when her feed ran out.
I am not concerned about her or her posting history/issuses; I am concerned about a drake who is being used as an experiment at the (potential) cost to his health and well being. It is so unnecessary
