Who's laying?

I am getting between 5 and 7 eggs a day in the nest boxes but I do know some are laying elsewhere - it's just a case of trying to find out where  . My little silkie x Claudette though has just decided to leave the trees and set up home in a coop so she is going to be broody for a few weeks again  - she has a pattern of lay 3 eggs then go broody for about 6 weeks, partial moult, lay 3 eggs and so on  .
