Bessie USED to quack. I swear it! I did the "pick up" test with everyone when their voices changed from peeps. She quacked. Then a couple weeks later, I noticed her talking and no sound came out. I watched her closely - but saw no respiratory symptoms. Then her voice came back, a little hoarse, but got stronger. Quacking like the other girls - a little quieter, but definitely 'wok wok wok' not the raspy 'breeep breeep breeep' grumbles my two drakes say. Now the boys have really lovely big C-shaped drake curls. Bessie has a pointy tail feather...that tilts up at the end. It's not a drake feather - but it's trying to be! And she sounds like the boys. I've heard of this happening in flocks with NO drakes. My guys are 15 weeks also - they do head-bobbing displays with the girls, but I haven't seen mounting yet. So what the heck is Bessie's deal? I don't care much, I just want everyone to have enough partners to be safe.
