I have just purchased 2 Pure Bred Lavender Blue Araucana hens, will they lay a different color egg each day??? I know they wont lay a pink egg one day then a blue one the other day, but will it go from a blue egg one day to a green egg to a paler blue, because that's whats happened over the last three days, but cant figure out if one hen lays a green egg and one lays a really noticeable blue egg to a really pale blue egg or what???
