I have assorted brown egglayers plus one leghorn that lays cream colored eggs. I also have a 4.5 month old EE pullet. About 3 weeks ago i found one, full sized, WHITE egg in the slightly elongated shape of one of my brown layers. I didn't know if that was my EE starting or not, and figured time would tell. Well, no more white eggs. Can a brown egg layer occasionally 'forget' to put the pigment on the eggshell? This was as white as it gets, not cream or light tan.
