i agree with others, I doubt it was the eggs.
and as for people not really thinking there is a difference in fresh farm eggs and store bought cheap eggs. I like to go through a "mine aren't pumped with hormones" and "my chickens are happy healthy chickens that lay when and where they want to" type of speeches for the sceptics.
some just don't understand where the cheap eggs come from and how they get to the store. I say cheap eggs, because I don't group the organic and cage free in the same catagory. I just know about the hormone pumped, battery caged, production chickens, that lay way too many eggs for one chicken, in one day. I think people (or at least the ones i sell to) like to know that my chickens eat, drink and run around when ever they feel like. although mine are not organic, they are better than store bought and they are more interesting because they are different shades of brown!
what I love is when people tell me they like the taste of white eggs better than the brown eggs, and that's why they don't eat brown eggs. LMAO
then you have to explain to them that egg color has to do with the breed of chicken it came from, not nutritional value.
but before I got into this addiction with chickens, I didn't know much about the difference in eggs either. I always bought white, mainly because I grew up on them and didn't eat many brown eggs that I knew of. but now give me brown, white, green or blue!! I love them all!!
I really hope you get your 'customer' to realize that it wasn't your eggs and maybe you could throw in the next dozen for free! good luck!
