Hello and welcome to BYC! 
I had egg eaters in my flock as well. Excellent advice given above. Things to do....Curtains, fake eggs in the boxes, collect eggs often, a good balanced diet, oyster shell on the side. Make sure they are putting on a hard shell, this is how it starts, somebody lays a thin shelled egg, it gets cracked open and a delicious treat pours out if it. If any of them continue to have trouble, use liquid Caltrate, orally, once a day for 1 week. It took my flock a couple few weeks, but eventually the egg eating stopped permanently. Good luck!
