Hens and Roosters can become bored easily and start egg eating. Its a hard habit to break. You can try the dish soap filled egg, move them to another pen or do anything that might change the environment. Change the nest to a blind nest or trap nest might help. But most of all make sure they don't want for anything. Make sure they have oyster shell and granite grit. Give them plenty of green stuff, cabbage, free range or anything to occupy their time. I seem to do better with crumbles rather than pellets. It takes a little longer for them to eat with crumbles. They waste more if your not careful. Good Luck!
