A friend is bringing me some Sebastopol eggs from out of town and I need to know how many to tell her to bring? I have a new Octagon 20 eco and the Brinsea website says 9-12 goose eggs fit... Well which is it those of you who have filled yours with Seb eggs? Is it 9 or 12??? I hate for her to bring to many and me not be able to take them all, or even worse not enough and I have empty space where I could have a gosling growing..... Any advice would be helpful... Thanks
