Hello, It has happened from time to time that one of the picnic eggs has broken. We have a weekly consumption of 4 x 6 packs. Calculated over the year, that makes approx. 6 - 8 defective eggs. At the beginning of last week, however, an egg was defective in one pack and again yesterday. As far as I remember, it's mostly the blue and green ones that are defective. I haven't said anything so far, but one defective egg in each of two consecutive packs is quite a lot. Kind regards, CH Buddy
