Does a chickens diet have anything to do with an eggs color. 4 of my pullets started laying last week and all the eggs have been a different shade of brown and size. So far about 3 from each hen. But I just got one out of the nest that was tan. I don't have a clue which hen did it. I also have 3 BO's that haven't started. Could one of them snuck in and layed it? The hens I know that are laying is 2 RIR, a Wyandotte, and a Black Sexlink. This one I can't figure out. Ideas?
