OK guys, I have 4 pullets. Until last week, only 3 were laying, and I was eagerly awaiting the 1st egg from the 4th, as she is an EE, and I really wanted blue/green eggs. Well, early last week I returned home from work to find 4 brown eggs in the nest box! Very dissapointed, and decided to find some guaranteed blue egg layers. Yesterday, my youngest EE emerged from the nest box, and when I went out to collect the egg, there was a beautiful robins blue egg there! Is it possible that her first few eggs were brown, and have now turned blue with a bit of maturity? Is it possible that one of the other girls laid 2 eggs in one morning? I really don't know what to think.
