I was making muffins today and i always open my eggs in a bowl before i put them in the matter because of different reasons. Anyway i have notice this egg it looks to me as if it is fertile. But i bought my dozen of eggs from no frills which is a large grocery store. I thought that you couldnt buy fertile from any store unless it is farm raise and it says so. I also made cookies after the muffins today.It called for 2 eggs. The other two are the same way. what are your thoughts on this.?
