Old hen picking on pullets

[RoyalCoopMom]

OK now I am truly baffled. Olive laid her 12th egg in 12 days this morning. Then laid again this afternoon. The eggs are exactly the same! That's 13 eggs in 12 days. I have 4 pullets not laying yet but the only possible contributor would be the easter egger. Faverolle, golden comet and the welsummer should all be brown.
