Hey Amy,
I am so sorry the carton did not work out for you.
We have our dimenisons listed on our website for what size eggs they fit in. The cell dimensions are: (WxH): 2.75' x 4.00' - plenty of our goose and turkey egg customers use these.
If you need help finding something more suitable let us know. I also reccomend trying out our duck egg cartons if these are too big for you.
I have attached a link to them here: https://www.eggcartons.com/collections/duck-egg-cartons
