Hi all, I posted a few weeks back looking for sex guesses for the ducks. Both my rouens have a very similar quack but now Ruth is developing a white ring around her neck and her head is more green-where Betty's is more brown. Also Ruth has a black bit on 'her' nose and Betty doesn't. I'm pretty confused and I think Ruth may also be confused . Anyone care to take another guess? Not the best photos but was trying to get them both so it's easier to compare. They're very camera shy AND it was dark out but you can just about see the white ring on Ruth and you can see the black bit on 'her' beak. But-like I said-their quacks sound VERY similar. Betty is the noisiest but they have the same 'tone/depth' unlike the pekins which have an obvious difference.
