I got my first egg this Satuday, and have gotten one every day since from my 6mo. barred rock, Ester. This morning I decided to have two of Ester's eggs for breakfast, and to give my dog a fried egg too, except his would be a store bought one we still have. From reading BYC I knew to expect a yolk color difference, Ester's egg yolks were more orange while the store bought egg yolk was more yellow. I also noticed Ester's egg was a lot harder to crack, thicker shell. Also, Ester's egg seemed to have more of a membrane on the inside shell. Just wondering why there are these differences between Ester's eggs and the store bought. Is it related to the age of the egg-- Ester's eggs are only a few days old? Thanks. ps- Ester's eggs were the best I've ever tasted!
