well, i wanted to call them Dandy and Daphne (although i'm still a bit smitten with Cheese and Quackers) but my Aunt is staying with me at the moment and she got the final choice, and went for Fred and Wilma!
some fab suggestions on here, thanks peeps!
Mr and Mrs Duck are very happy this morning, she whizzed over the fence away from him twice (from garden into yard) so i've trimmed her flight feathers and she's stuck with him!
