No Eggs Yet

The girls are 25 weeks old today - but we haven't seen any eggs yet. I placed some fake eggs in the nest boxes hoping to entice them to their laying spot. I know that they have been in there - moving the eggs around - but that is about it. Yesterday I decided to take out the fake eggs as I was worried that they were trying to hatch those instead of laying their own. I hope finding a new home for Stevie hasn't thrown them off their game. This is all new to me...so I would appreciate any input as to whether we should be worried or not.
