We've got some 6-7 week old muscovies. Last week, one of them started "crying" almost continuously, sometimes for hours at a time. Around the same time this started, she had a limp for a few days. I picked her up and examined her and couldn't find any cuts or abrasions and she didn't seem to react to me touching any particular part of her. She's not limping anymore, but I can't tell if she's crying because she's in pain or not. She seems to be picked on a bit by some of the other ducks, but she always spends time with the other 4 ducklings that she was born with and I don't see any problems there. So...why is my duck crying and is she ever going to stop? She's my favorite of this bunch and I really want to keep her, but she is driving me nuts.
