Well, my guys are about 2 and a half months old and HUGE! I know they aren't full grown yet. I still can't tell which are boys and which are girls though. I hear rasps and quacks, but they always travel as a pack and look the same anyway. Bwahaha! They aren't very friendly, but since I moved them into the bigger pen they have been not QUITE as scared of me. I guess I won't ever get to snuggle with ducks.
I feel your pain.... I'm a wannabe duck snuggler also. Hang in there. I'm not giving up on mine yet
