At about three weeks, someone started honking. Then over the next month or so, everybody started honking, then quacking, except it wasn't really quacking. My Runners make this ah AH AH Ah sound most of the time, and quacks are for when they are startled.
Ah, the duckling leg stretch.... it was normal for our Runners.
Why am I seeing Buffs every time I look at a duckling tonight????? Maybe I have Buff brain.
