So I was given an already pregnant doe, the women I got her from told us it would be her first litter, she did build a nest and when I palpated her I could feel movement and 2 nights ago she pulled fur and last night when I came home she was bleeding and having contractions it is now the next day and she has not delivered anything I am now thinking she has a kit stuck inside as she is still having contractions is there anything I can do to help her pass the kit?
