Silver-laced Hamburg stop laying or changed color of egg?

[rmdudley]

my silver-laced Hamburg used to lay small white eggs. She is my only white egg layer. A few months ago she stopped abruptly without any apparent reason. I have 5 chickens and occasionally find 5 eggs in my hen house. They are not day old eggs as I collect every day. I'm not seeing any white eggs all brown and one blue. Is it possible she is laying a different color egg?
