I think your EE will go next.  Then as follows.  
1st - EE 
2nd - BSF
3rd - RIR
4th - SS and Cochin
Just keep putting your EE's in the box and stuff the golf balls under their butts.  I really really really want to hatch some eggs.
As for the eggs rollin out...could they be hiding them?  Have you looked in every single nook and cranny and hole?  My Cochin loves to lay in corners and in rocks.  We can always tell her eggs apart from the others because she gets her "fluff" stuck to the egg.
