My SLW laid a pretty big egg here a while back...94 grams I do believe! I thought that was a whopper...until I collected this one... The egg on the left is from my White Pekin duck, it weighs 102.9 grams/ 3.63 oz...My SLW is on the right at 107.1 grams/ 3.77 oz. that poor girl...all I can think is... OUCH !!!!
