I discovered an absolutely large Campbell egg in the coop today. Now I have chickens, muscovy and the campbells laying right now. The egg weighed on a postal scale was 125 grams or 4.4 ounces. It is massive. see what you think. Is that a normal size as I only got the Khaki Campells yesterday and the eggs I got from them yesterday were just slightly bigger than muscovy eggs. I'm just starting to market my excess eggs but hey you don't get egg cartons to hold eggs like that.
