What beautiful photos! Is the duck at the front of the 4th photo a female? It looks almost exactly like our Daisy. We've just become a little unsure if our Daisy is a female (she's almost 6 weeks old) as she hardly says a word, so we can't judge her 'quack'. We also have a magpie duck (same age) who we were convinced was a boy, but he has just started quacking VERY loudly, without the rasp! Perhaps Daisy has decided that Arlo quacks enough for the both of them. If your duck in the 4th photo is a girl, then I will still hold out hope!!
