I have one who's got me guessing too. I bred Potsie to be due 1-28/2-2 and then she came in heat again so I bred her and she would be due 2-21. She's just starting to get a little pouch on her udder, though looking at it there's nothing there. My other doe, Contredanse, who has to be due 1-28 or 2-2 since that's the only time she was bred has a softball sized udder already. Daisy who's a ff also has just a tiny bit of something starting and due 2-3 so I have been questioning Potsie's due date.
