Just found out my ducks aren't as old as the guy originally told me. They are closer to 10-11 months old.. ish. He could remember specifically which hatch they are from. (Got them from my neighbour.) Their warts & colouring started filling in nicely once the warm weather hit & pond-grazing began. Will have to get some photos. Nothing makes me laugh more than seeing the ducks running through the tall grass to come & see us for 'treats' (aka duck layer feed, some corn, some worms...)
