My butterscotch duck was missing this morning and I found her under the wheelbarrow,I have found a couple of eggs there lately,so I thought she was just laying so I left her there . I went out this afternoon and checked and there was no egg and she was sitting on her own , when she got up to walk I saw that there was like a White string hanging from her vent.I picked her up and it looks like membrane from an egg , it is about 1and a quarter inches long , I tried to gently pull it but it is stuck .what do I do ? I have her in the warm bath at the moment . She is only starting to lay as she was last years bird. I have searched this site but can't find anything about ducks being egg bound
